How from Solution to make Coagulation.
COagulation:* 1.1 put the sulphur Solis into the
viol-glasse closse stopped, and set it in the
foresaid first degree of heat for eight dayes,* 1.2
till it bee almost exsiccat with the humidity of lac
virginis that was left inherent in it;* 1.3 and then open
the glasse and poure thereon asmuch of the lac as is
the weight of the caput corui,* 1.4 and mixing it well, let
it stand one or two dayes till they both be coagulat
in one,* 1.5 and become almost dry; and so forth doe
thus till all the lac bee drunke up, which will be a∣bout
the space of 90. dayes more or lesse, accor∣ding

as the matter is of quicknesse and activity; and
if this lac or aqua vitae bee suspected to have con∣tracted
any dulnesse and superfluous humidity
while it was in the former worke of solution: in
that case it is to bee prepared againe, quickned,
sharpned, and made fitter for this present worke of
Coagulation.

Coagulat as is said, the Coagulation must yet goe
on, and with the second degree of heat for the
space of a month, the matter Coagulat must stand
in that heat, till there appeare cauda pavonis, that is,
a variety and multitude of colours; and at length it
will turne to a white colour, called corpus album,
sulphur album, coagulatum album, terra philosopho∣rum,
&c.
