with sifted Ashes, laying a polish'd Glass upon the Mouth of the
Glass.

My Child, know that your Matter is become fixt with the Stone in the
solution, make an indifferent hot fire in the furnace, so hot as the
heat of the Sun at _Midsummer_, or somewhat hotter; till the Matter
begin to be yellow, then go on with the Fire from one degree to another,
till you have a perfect yellow, then increase the Fire from one degree
to another, till you have a perfect redness, which is quickly done, in
half the time for the colour to come, and in the multiplication, but
operate as before in the beginning, and poure Paradise water upon the
Stone, as was taught you before in this Work, boil and mortifie it in
every point to a perfect redness as hath been taught.

Then may you again take half of it out, and make projection therewith,
and multiply the other half again in all points as abovesaid, so may you
always continue working.

Now I will teach you the other way, and the best that is to water your
red fixt Stone or powder with the red Oil, that it be fusible; you must
know how much your red powder weighs, then take half the weight of your
red Oil, to the full weight of the Stone, and poure it upon the red
powder, and when the Oil is poured into the Glass, you may set a small
head on, upon a Furnace in sifted Ashes, joining a Receiver to the Nose
of the head, make a small fire under it, as the heat of the Sun in
_March_, and no hotter; for there is yet some moisture of the Vinegar in
the Oil, that it may be abstracted, continue it in that heat, that can
perceive no moisture in the Head, then augment the fire a little, as the
heat of the Sun at _Midsummer_, and if there be yet more moisture in it,
you will perceive it in the head, but if you perceive it not in 6 or 8
days, then take the head off, and lay the polish'd Glass again upon the
mouth of your Glass, increase the fire, that you can scarce endure your
hand or finger in the Ashes an _Ave-Mary_ while, continue the fire in
that heat till the red Oil be all fixt with the Powder in the Glass,
which you may know thus;

Take a little of the powder out of the Glass, lay it on a glowing Silver
Plate, if the powder melts as wax, and penetrates through the Plate as
Oil doth through a dry Leather, and makes it Gold throughout, as far as
the powder went, then is the Stone finish'd, and if it do not this, you
must then let it stand in that heat till it do so without fuming.

Now, my Chi
