- Rulandus: The Exaltation of a Matter into its essential
part by means of a ferment which penetrates the entire mass, and operates
therein in a peculiar manner, acting immediately on the spiritual nature.
Thus, it is found that out of an agent of medicinal fermentations which
is of little symbolic value, the most noble substance is produced which
nature suffers us to attain. But it exists much more abundantly in metals,
the nature of which is more akin to it. It takes its name from its likeness
to a fermented mass. Or:
Fermentation is the incorporation of a fermenting substance with a substance
which is to be fermented. For even as a small modicum of ferment, or yeast,
can leaven a large mass of flour, so does the chemical ferment assimilate
itself to the thing that is to be fermented. Whatsoever be the nature of
the ferment, of such is the fermented matter. By ferment the philosophers
understand a true body and a true matter, which, united to its proper Mercury,
convert it into the nature thereof. Some will have that the stone itself
is the ferment of a perfect body. For when the stone is so subtle, as the
philosophers term it, that when it is projected over an imperfect body
it floats after the manner of an oil, without combining therewith, we need
some other body, which still retains traces of its former affinity therewith,
which shall receive and introduce it into other bodies.
- Rulandus: is Elixir, a Leaven, which makes the body spongy,
which ascends, and the spirit finds place, so that it may be prepared to
be baked, since now the meal is no leaven, and the meal and the water and
the whole dough are thoroughly leavened, and indeed mere leaven, therefore
also is the stone itself the Ferment, yet are gold and mercury also called
2. Hermes says: Ferment displays the work, otherwise nothing comes of
3. Gebir says (L. Form., c. 19) : Resolve Sun and Moon into dry
water; this is what is called Mercury. Also the twelfth part of the water
holds a part of the perfect body. After forty days you will find the body
resolved into water. The sign of the complete dissolution is the blackness
which appears above, and is our Mercury, which we take for a Ferment.
4. The Paste which we wish to Ferment, which we extract from imperfect
bodies, the white out of Saturn and Jove, the red out of Mars and Venus;
but every body shall be dissolved in its own ferment.
5. The English Richard says: Take white Ferment, but for the red take
red; nevertheless, the red can give white.
6. Gebir says: After the fermentation, it must be shut up; thus the
material is brought to the white stage in forty days; to the red stage
in ninety days; in one vessel and operation.
7. Lully says: The ordinary gold cannot be a Ferment, for it must have
an actual, effectual, and working power, and be full of spirit; yet it
is also called Ferment, and silver is called White Ferment. Or:
Ferment is a firm, and, as it were, a fixed matter, which prepares a
substance after its own nature to become of its own fixed condition, which
also before it was prepared had itself no greater fixity ; as, for example,
Ferment of Bread is flour condensed into a paste which will also communicate
the fermented state to other flour.

- Rulandus: Iron, is a Metal, for the most part, of a livid colour,
but having also a certain quality of redness and a kind of impure whiteness,
while it is also hard in texture. If fixed, earthy sulphur be mixed with
fixed, earthy quicksilver, neither being pure, but partaking of a livid
whiteness, and if the sulphur predominate, then iron results. In fine,
if the quicksilver be porous, terrene, and impure; and if the sulphur be
also impure, fetid, and terrene, then their copulation produces iron. This
metal is attributed to Mars by the chemists, and is so called, because
of its many uses in war. By some the stone Sideritis is called Iron Filing,
or Scale of Iron, and the magnet, which attracts iron, sometimes has the
same name. Now, iron is of two kinds, native and melted, or excocted. The
native is pure, and is found in mines, either in grains or nuggets. The
second species is that which is produced in the forges of Germany after
one of two manners: either from iron ore, as it is in a certain valley
which takes its name from Kings, and in a number of other places. It is
to be noted that the same veins which produce iron frequently produce loadstone,
which has affinity with iron. Iron is also melted out of ruddy ferruginous
earth, among other places, in Silesia, where I have myself witnessed the
process in a foundry not far from Berlin, and am in a position to affirm
that, even as some Pyrites is hard, solid, and close of grain, while other
is brittle, and easily pounded, so also some iron ore is solid, and requires
much melting, while some is brittle and like a rusty corroded earth, which
can be operated on with little fire, as is the case with the rich ore of
Silesia, and the earth of Marchia and Nicia. There are also very ancient
mines of iron which were worked, as Tacitus informs us, by the Goths of
Gaul. In Germany the first mines worked were those of iron. For the rest,
concerning what iron is good and what bad, I refer to the smiths. If I
mistake not, in Thuringia the Dylmeratian species is commended, while that
which is derived from a vitreous ore is condemned for its brittleness.
On the varieties of iron and its metallic alloys, consult Pliny (l. 34,
c. 14, 15, etc.), and Dioscorides (1. 5, c. 46), who treats of Iron Rust
and its virtues. Iron rust has a powerful, restringent, medical quality,
and is also binding and drying. It is warm and dry in the second degree.
With it Hercules is said to have healed the wound of Telephus, to which
occurrence an allusion is made by Ovid in his first elegy: " Either no
one, or Achilles only, who inflicted the wounds, can heal me ". Dioscorides
also (l.c.) treats of Recrement of Iron, or Iron Slag, which he also calls
Scoria and Excrement of Iron, or the Stone Sideritis, the German Thunderstone
(Arolite). For even as all the higher metals yield recrement when melted,
so also does iron. Thus we have:
of Copper:Copper Slag; of Silver: Silver Slag;
of Iron: Iron Slag; of Lead: Lead Slag.
Recrement of Iron has the same kind of virtue as Rust of Iron, but it
is of less efficacy. This will apply also to that broad and thin scaling
of iron which is obtained by hammering. For the rest, on these subjects,
consult the Arabian writers, Serapion, and also Nicander, who calls Scoria
of Iron by the name of Iron Feces, and says that it is an antidote to Belladonna,
which Dioscorides appropriates after his usual fashion.

manners; he refers also to its medical potency, which is abstergent and

- Rulandus: i.e., the Son, the Child. According to Morien it has
a father and mother, by whom it is nourished, and is one with them, yet
where the chicken is not hatched and born it dies in the egg, just as bread
which is sufficiently baked, and soap which is sufficiently melted.
2. When he is born, he wants food and nouruishment. The nourishment
is the augment. When the material is nourished by means of the ferment,
then the child becomes a seed again.
3. The Stone is at first the old man, then young; then the strength
and working is like those of youths full of blood and fighting power. The
aged are grey and white. At first the Egyptian is moist and white, afterwards
red and dry. Therefore it is said: The son killed the father; the father
must die; the son must be born; die with one another and so rise again,
according to the saying: He who dies with me must live with me. The Sun
kills the Mercury and hardens it.
4. His nourishment is first in the bath or in the matrix of the earth,
which receives and nourishes until body and soul become one thing, and
of a fixed nature. Bernard says: The feminine germ nourishes the Stone,
not by dissolution but by addition, thereby it grows strong and great.
5. Turba (fol. 89): Take the white tree; build about it a round
and gloomy house; surround it with a tower and put therein a centenarian.
Then shut it up so that no wind or dust can get to him. Leave him there
eight days. I say to you that the same man must not cease to eat of the
fruit of the tree until he grows young again. 0 what a wonderful quality!
Here is the father become a son, and born again.

- Rulandus: is Subduction by Filtration in a Colander; but
this process in the chymical filter may be also called Straining, or Percolation
; it is performed chiefly in operation upon moist substances, from which
the aqueous part passes through the colander, and those which are oily
or thick are left behind. The practice is principally this. A sheet of
commercial paper [carte emporetica], or a rough basket, is shaped into
the form of a bag, or applied to the vessel, after the manner of a funnel,
etc. The infused liquid passes out by degrees, to be distilled into its
receptacle, whence this operation is called Distillation by the Colander.
- Rulandus: is a Frigid Descension, the aqueous portions of
the matter treated, passing through the colander, or filter, or funnel,

It is also elevated and produced from the centre and inmost parts, that
it may coagulate in a dry form at the top. The spirituous Flos, or Flower,
is the substance of a thing. Every flower of a matter is in itself volatile
and spirituous, although it is possible to fix it by a masterly skill,
and to bring it to the nature of Turbith (which see).

It is a substance mentioned by Paracelsus, and there is supposed to have
been a mistake in his manuscript. For myself, I understand it to be the
Flower of Moss-nut [? Florem muscatce nucis. Red Emuscata.] Others suppose
it to be Flower Extract of Celandine.
- Rulandus: i.e., Flame.
- Rulandus: are Stones similar to gems, but less hard. They are
called Fluors by the metallurgists, because they melt and flow under the
heat of a fire, even as ice does in the sun. But there are also species
which dissolve under the influence of a spirit, and of the air. Theophrastus,
if indeed he is referring to these things, calls them *** [Greek], because
they are produced in a terrene flux. But I believe that they were unknown
to all the ancients. In order that the various species may be better known,
we subjoin them in the interest of the student. Fluors are the rudiments
of gems, and like unto the same in appearance; they are found in mines
1. Of red colour. At first sight this kind is like rude reddish silver,
or carbuncle, but it is of less effulgence. Also the carbuncle withstands
fire, whereas the Fluor melts immediately under its influence.
2. Of pale purple colour. This kind is at first sight like pale green
amethysts, such as are found in Bohemia, and certainly are not very different
from these. As uncritical persons are deluded by the similarity they are
unable to judge amethysts. They are unlawfully set in rings and sold as
the genuine stone.
3. Of white colour, looking like crystal.
4. Of clay colour, looking like topaz.
5. Of ashen colour.
6. Of semi-black colour. But there are also Fluors of other colours,
if we look closely into this matter. It is the custom, when metals are
smelted, to treat them and cast them in. The material is restored in a
more fluid state, even as with the kind of stone out of which pyrites is
made. If the experiment were made, I consider that the best colours would
be obtained from Fluors thus treated.
1. Showing ruddy in white, sexangular, and pellucid.
2. Long red Fluors, like an upright beam, whence are obtained those
small black stones from which White Lead is obtained.

- FORNAX ANEMIA
- Rulandus: is an Oven shaped after the manner of a tripod,
with a conistery and a grate, divided into two parts by a gridiron. The
conistery is made fast by an iron gate, by which air can enter. The grate
is open and covered with coarse clay. The free space is called Ergastulum.
The matters are frequently prepared, or treated, in a frying pan, baking
dish, saucepan, triangular vessel, etc., so that they may be set upon the
burning coals, or quickly removed therefrom. Frequently the fire is increased
by a fan, or bellows, but usually a proper draught of air is sufficient.
It should also be said that the gate of the conistery can be opened by
the current of wind or air. The only other exit should be that of the shaft
or chimney; more especially when a matter has to be melted or calcined
by a great heat.

- Rulandus: Painter's Black, Cream-soot, is made in several ways
and of many materials; among us, out of pitch. Dioscorides says that it
is obtained from glassblowers. Its medical virtue is astringent and consuming.
- FULIGO METALLORUM
- Rulandus: Properly Arsenic, but it often signifies
- Rulandus: In the present connection is the Flowers of Cupellated
Silver, in the cleansing thereof with lead. Consequently, Metallic Fulmination
is, especially with the higher metals, a process of purging.
- Rulandus: is a Metallic Gradation, with Excoction, educing
the pure part, the perfection thereof being indicated by an irradiating
splendour. Hence the name of the operation, because there is a coruscation
accompanied, like lightning, with a reverberating noise. After the foreign
substances have been separated, a kind of sulphureous cloud appears on
the surface, followed by a purplish splendour, which is called the brightness,
lightning, or flow. When this has passed away, the matter has already begun
to grow cool.
- FULTURAE NATIVE VEL FORNICES
- Rulandus: Natural Supports or Arches.
- Rulandus: Fumigation is Calcination by an aerial and corroding
smoke. It is performed in diverse manner, the nobler metals by an afflatus
of fused lead or artificial quicksilver; the fragile parts are given up,
and subsequently triturated by rubbing with salt.
- Rulandus: is the Scoria, an incrustation on the floor, yet properly
that which arises and brings the body with it. For there are two kinds
of smoke, which mix with the earth, make the stars fall from heaven, make
also comets and rainbows about the sun and moon. When the batia finds a
mineral matter, then it is to the smallest extent mingled with it. It also
becomes fixed and a metal, but should the batia not find any, then it becomes
a mercury; but the mineral power which it ought to find is clear sulphur
washed, and partially fixed, and it is found in the extracted stones, and
in sand. It shines like silver, and because nothing can be produced without
this, it is found in every place wherein metals are generated. Consequently,
metal which contains much sulphur is called the lake of the generation
- FUMUS ALBUS
- Rulandus: is Mercury, the Soul and the Tincture, Heavenly
Water, the Quintessence of Venus; this smoke conducts the colour of the
gold by a dry process into the height. Then the snake climbs up into the
tree, and finds the mother with two children, and devours them all. That
is to say, the smoke rises over itself, and finds two sulphurs with the
Mercury. It dissolves all, generates it in itself, becomes fixed, and is
petrified. The white smoke is the soul of the dissolved bodies; it imparts
life and whiteness.

- Rulandus: Covered Furnaces; those which have a roof.
A Covered Furnace is either simple or compound.
A Simple Furnace is that which stands by itself, and has no connection
with any other furnace. It may be either a calcinating or dissolving furnace.
A Calcining Furnace is one that is used for calcination. It may be a
welding or reverberatory furnace.
A Welding Furnace is one in which the fire is conveniently arranged
for welding substances. It would be possible to mention various kinds of
furnaces for conducting this operation, but that which I am now about to
describe is more satisfactory than all the rest, both on account of its
continuous fire, and also because of the easy regulation of the degrees
of the same. A square brick wall is built, having internal breadth of a
cubit, and extending upwards to the first compartment a height of one foot,
thus forming the ash-pan. It extends to the second compartment one foot,
thus completing the Ergasterium. Next, the furnace should incline towards
the tower a height of one foot. Next, from the top of this furnace we must
erect a tower three feet in height, and having an internal capacity of
one foot. The height of the furnace so constructed will be six feet or
three cubits. But two doors must be left in the interior wall-one in the
ash-pan being a third of a cubit in length and the sixth of a cubit in
breadth, convenient for removing ashes and inducing currents of air ; the
other door in the oven must be nine inches. Between these doors an iron
grate is placed, and over it we set an earthenware plate, which can be
surmounted by an archshaped roof. Coals supplied through the upright tower
burn upon this roof. Moreover, four apertures must be made in each wall,
so that on any side the coals can be stirred by a poker. Also, let the
tower have an aperture at the top about the breadth of a little finger,
which in most cases is to be left open, so that the fire may draw the air
which sustains it. The outer doors and apertures are duly closed by their
lids, so that the furnace may sustain the fire for an uninterrupted space
of twenty-four hours, according as the work requires.
The Reverberatory Furnace is that wherein the matter is calcined by
bounding or resilient flame. It is constructed in the following fashion.
Let a brick wall of oblong shape, and of the height of one foot, be erected
to serve as an ash-pan, having an aperture of the breadth of four fingers,
which will serve as a door for the removal of ashes. Place upon this wall
a grate obliquely, and over that let there be a wall extending to the height
of one foot, to serve as an oven. In the ash-pan there must be a door four
fingers broad through which the ashes can be removed. Above it there must
be another door in the wall of the grate, wherein wood can be put. After
these arrangements have been completed, let a sort of gallery or terrace
[solarium] be constructed of bricks, which shall not be in contact with
the posterior wall, and shall be three fingers in breadth. Through the
aperture thus left the flame will make its way, and being stopped at the
arched roof, will reverberate upon the matter. We next leave a moderately
sized door in the interior partition above the gallery, through which the
matter to be reverberated upon may be put in and taken out. We cover the
remaining portion of the furnace with an arched roof, which is a little
lower down than the other part. We cover the anterior and posterior portions
of the furnace, and strengthen them with walls of brick, after having left
four ventilators, side by side, being of the space of two fingers, in the
said upper door. By means of these ventilators it is possible to regulate
the fire readily and conveniently, to increase and diminish the heat at
will, as the operation requires. When everything has been constructed after
this fashion, we make a lid to fit each down, and adjust it thereto. The
furnace is then ready for use.
The Simple Dissolving Furnace, dissolves matter by its power of resolving
the coarse into the refined. It may be either an ascending or descending
An Ascending Furnace is that which dissolves by ascending. It is either
dry or humid.
The Dry Furnace is a vessel containing the matter, the vessel in question
not being put into water. The dissolution is effected by means of an external
moisture. It takes place in a bladder and sand melting box.
The Bladder Furnace is that which serves for dissolving the matter in
a bladder. It is as follows: Four walls are erected in a square, being
of the height of one foot (the breadth varying according to the capacity
of the bladder), and this serves as an ash-pan. But from one side of the
bottom two fragments are so placed at the corners as to leave in their
midst a vacant space of six fingers' breadth and the same height for the
ash-pan, which completely fills up the space designed for it. Over this
structure we must place iron bars to form a grate, and then we shall have
finished with the ash-pan. Above this an oven is to be constructed by means
of similar walls, eighteen inches high, a door being left in the centre
of the furnace by means of which the coals can be manipulated. Over this
wall-structure we place an iron bar, which holds the bladder suspended.
Having made this structure, the wall is continued to the height of the
bladder. It is to be noted that the furnace is to be constructed with such
a capacity that a space of at least two fingers' breadth shall exist between
the furnace and the vessel, so that the latter may be properly encircled
by the heat. Having put in the vessel we cover the furnace ; nevertheless,
we allow the orifice of the bladder to protrude, and the four ventilators
are also left open. Finally, we construct a lid for each hole and adjust
The Sand Vessel Furnace is that which dissolves metals by means of a
sand box. It is made after the manner of the furnace described above; there
is no difference in the structure, except that instead of a bladder, we
place therein a melting, or any other vessel containing the matter, and
we keep a watch on the furnace. But if we wish to dissolve anything by
an open fire, i.e., without a vessel of sand, and by inclining the other
vessel which contains the matter upon its side, let the furnace have a
vacant space in one of its walls, four or six fingers wide, according to
circumstances, and of a suitable capacity. Such a furnace is of great use
in all kinds of dissolutions, either when performed by ashes, by sand,
or by iron, or even by naked fire.
- Rulandus: A place wherein the fire for chemically operating
upon a matter may be properly and conveniently placed. The furnace may
be either open or closed. An Open Furnace is one which has the upper part
open. This kind may be either a testing or blasting furnace.
A Testing or Assaying Furnace is a furnace wherein the nobler metals
are refined and searched, or, to use a more correct and technical term,
are fulminated. It is constructed of potter's earth, iron plates, or tiles.
An iron or earthenware plate is taken, and a four-sided structure is built,
in such a way that its base is eleven feet square, but its height is sixteen
feet. After the first eight feet of its height it becomes narrower by four
feet, yet must the mouth of the furnace be seven feet wide. It is correct
also for the plates to have a thickness of one foot and a half, but the
floor and the base should be potter's clay, half a foot thick. Having erected
this building, we measure three feet upwards and four feet along. This
constitutes the lower doorway. From the post of this doorway a wall is
continued for two feet, which takes up the space between the first door
and that next to be mentioned. Measuring three feet and a half above, and
four feet along, we have a convenient door for taking things out and putting
them in. We must next proceed to bore a certain small hole at a foot's
distance in the centre a hole in which the little finger can be placed,
this is convenient for the poker whereby the coals are stirred. Moreover,
three-quarters of a foot away, and at the extremity of the door, partitions
must be placed on the right and left, where the two holes are of the breadth
of an ordinary finger. Into these holes, with which two others should correspond
in the opposite wall, are placed iron rods, extending to the breadth of
four fingers along the wall. Lids or stoppers must be fitted to either
door, having a handle, so that they can be removed and replaced. The upper
of these lids must have an oblong hole, so that when the door is closed
the interior may yet be visible. Let the lower lid be provided with a circular
and larger hole, so that the fire may attract the air which sustains it.
Over the rods let an earthenware plate be placed, hollowed out on three
sides, but intact on the fourth side, and fitting accurately to the anterior
wall. Then the floor of the compartment must be fixed, and an arch-shaped
roof placed above, which must be distant two feet and a half from the side
and back. Further, let a circular hole-as it were, another door-be cut
out, to provide air. When everything has been constructed on this model
for the furnace, before it is baked, let the iron plates which constitute
the furnace be properly fastened together and riveted. Let, finally, the
whole construction be dried in a sunny place, and properly baked by a potter.
This manner of making a furnace is the most convenient possible, both because
it is not easily choked up with ashes, and because it is sufficient for
all assaying purposes, far excelling all others in the facility with which
the fire can be directed.
A Blasting Furnace, or Anemia, is an open furnace wherein, by means
of a current of air which increases the flame, the minerals are liquefied
and melted. Should the metals be exceptionally difficult to fuse, so that
the blast cannot produce sufficient heat, or the worker desires to melt
something very quickly, a bellows can be conveniently attached to the furnace,
to increase the fire and accelerate the melting. The blasting furnace may
be constructed with its own bellows in the following fashion. Erect four
walls, a foot apart either way, and a cubit in height, to serve as an ash-pan.
On either side of the ash-pan let there be a door, by which the fire can
draw the air, and the ashes be removed. Moreover, above the ash-pan, let
iron bars be arranged to form a grate, for holding the coals and the vessel
placed therein. Let there be another hole of the breadth of a finger beneath
the grate, through which the beak of the bellows can pass. Then let the
furnace have an oven added thereto. When it is sufficiently dried by coal-dust,
and washed over with mud mingled with water, the bellows may be affixed.
This furnace, in case of necessity, may also be used for calcination.
- FURNUS BALNEI
- Rulandus: is that in which we dissolve the matter when
hot in the bronze vessel which contains it. This furnace is built in the
same way as the two others, and instead of a bladder or sand box, a brazen
box made for the purpose is substituted. But in the vapour bath another
vessel of copper made in the following manner is fixed to the top. The
vessel is round, and two or three feet in height, the base being comprised
in the interior of the ahenum, and the whole arrangement is so exactly
adjusted that no vapour can escape. From one side of this vessel a canal
or pipe projects, the lower end of which is in contact with the ahenum,
so that, if necessary, fresh water can be poured through it. In close proximity
to the ahenum, this vessel has a kind of twist upon which a perforated
plate something like a diaphragm is placed, containing the vessels. It
sometimes happens that more things require to be digested than can be contained
in one vessel, whence it is necessary, in order to supply this deficiency,
that a second and even a third vessel should be added, according to the
need of the moment, and the number of things to be digested. We fix on
the top of the vessel a copper lid, which fits exactly, lest any vapour
should escape. But when we wish to abstract anything by means of the vapour
bath, we do not need this vessel. A cucurbit is placed in a deeper ahenum,
care being taken that no water shall reach the glass. It is necessary,
however, that the vapour should surround and heat it. As a further precaution,
let the lid itself have a cover.
A Descending Furnace is that whereby we drive the moisture downward,
and so dissolve the matter. Walls are erected for the ashpan, that the
containing vessel may be sheltered from the violence of the fire. Upon
the ashpan a grate is arranged with a circular aperture in the centre,
through which the orifice of the upper vessel may pass. The walls are continued
to form the oven, where also the ergasterium is constructed, and in this
the vessel is put reversed. Then, a fire of the required temperature being
sustained, dissolution takes place.
Composite Furnaces are those in which one fire is used for all. Such
are the Athanor and Acediae (time-saving) Furnaces.
The Time-Saving Furnace is that where many furnaces are sustained by
one fire with very little trouble. It takes its name from idleness, and
is called "Idle Henry" by the Germans. A round or square tower is erected
in the fashion before described, and we leave apertures over the grate
which conduct the heat to the side furnaces. There may be three, four,
or five of them. Iron stoppers must be provided, by which the heat can
be cut off or communicated. By the means of these separate holes another
furnace may be closely connected. Nevertheless, it is necessary that each
furnace should have its own particular ash-pan and pyreterium, with a separate
grate and chimney. By the help of these time-saving furnaces almost any
purpose can be accomplished.

- Rulandus: is Liquation by Heat.
- Rulandus: by Antimony is that process by which we separate true
gold not only from imperfect metals, but also from silver, and it is performed
in this manner. I take gold combined with other metals, and mix with it
three parts of pulverized antimony. I then place it inside a crucible which
will withstand fire, and this vessel I place in a blasting furnace. Afterwards
(if necessary, with the help of the bellows) I transfer the duly liquefied
substance into a heated pyramid, then, having struck the sides with a mallet,
the regulus containing the gold will settle itself at the top, and we strike
off the top with a mallet. The residual antimony contained in the pyramid
I again put to the fire and proceed as before, up to the third time, so
that all the gold may be taken from the antimony. Each metal regulus thus
obtained, having been put into an earthen vessel, and coals having been
piled on the top, I set a light to them just like the fire of a furnace,
and keep up the flame until all the antimony being evaporated, there is
a residue of pure unalloyed gold, which instantly solidifies.
