3 54 Of Things relating to Cbymtjlry,&c. Part IV. 
Apr. 3 - 1679- The firft of this kind was made by Mon- 
fieur Baldwin, a German Lawyer who gave it the Name 
above, but with no direction for the making of it. Nor 
doth he fo much as mention the Materials. 
I call it Solid , to didinguifh it from two Liquid kinds. 
The Author of one, fuppofed to be Mr. Ban. Kraft. The 
other invented by the Honourable Mr. Boyle $ which He 
calls the Aerial Nociiluca =, and whereof He hath lately 
published an excellent Bifcourfe. In who (c Laboratory, the 
folid kind was alfo made by his direction, feveral ways. 
Of the Procefs for This here, Dr. Stare fome years fince 
received a hint from Dr. Cbrijiian Conner ding., Arcbiater to 
the Duke of Zell. And not hearing of any one, amongit 
many that have try’d, belides thcfe Three, to have fuc- 
ceeded in the making of it, he hath imparted the following 
Account. 
Take good firm Chalk, ignite it in a Crucible , and then , 
powder it. Put into a pint or half a pint of drong Spirit of 
Nitre, Cochleatim , as much hereof, as will ferve well to fati- 
ate it, i. e. till it becomes fweetiih, and makes no Efervefcence 
upon the injection of the Chalk Then dilute this Liquor 
with fair Water, filtre it through a Paper, and fo evaporate 
it 111 a large Glafs, or glazed VefTel, or good Ha fan Crucible 
to a dry Salt. The preparation whereof may be perform’d 
in four hours: whereas I have feen a Pocefs, that would take 
as many Weeks to follow it. 
The main bufinefs lies in the good Enchirefis 5 about 
which thefe feveral Directions mud be carefully ob- 
ferv’d. 
Fird you mud prepare a VefTel of Clay, fomewhat like 
a (hallow Cofee-Bijh , of three, four, or five inches in Dia- 
metre, and an inch in depth, very well baked and neal d. 
Then place it under a Muffle, after the manner of a Refining 
Furnace, in the place where the Cuppels ufually dand: and 
fo make it red hot. Then put the prepared Salt into it, by 
little and little, not above 3i ff- or 3ij at a time. Keep the 
fire to that degree, which will fudice to make the Salt boil 
in the Dilh, fo as to fpread it felf every way, and creep up 
the Tides of it. Before the Salt, lad put in,’be confumed, be 
fure always to be ready, to make a new addition, otherwife 
your labour fo far is loll, and you mud begin again.
