It will be eaiy by this apparatus to perform the 
operation without any confiderabie lofs, provided the 
fire be well regulated. It is neceflary to make a very 
flow fire at firfl, in order to condenfe the volatile 
fumes ; for a great quantity of air is fet free, when 
the ingredients begin to a6f on one another. The fire 
fho’ild be rather flow for the firfl four or five hours, 
and then gradually encreafed, until the crucible be- 
comes moderately red hot ; in which date it is to be 
continued during the reft of the operation, which 
commonly lafts about fixteen hours from the begin- 
ning to the end. 
If this operation be performed for the fake of the 
Aurum mofaicum only, or for its fublimate, it may 
as well be done in a matrafs or body j and in that cafe 
there is no great lofs of the fublimate.
