98 The Triumphal Chariot of Antimony. 



Transparent white glass of Anti- 

 mony, after its commixture, is further 

 prepared as follows: Pound, together, 

 one part of Antimony till it becomes a 

 fine powder, and four parts of Vene- 

 tian borax ; melt in crucible till the 

 substances are in flux, when they will 

 become first yellow, and then white as 

 glass, for, under the continuous regimen 

 of the fire, the yellow here gives place 

 to the white, and a beautiful glass 

 results. The white colour is matured 

 as before, and is tested, in like man- 

 ner, by the insertion of a piece of cold 

 iron. 



There are many other ways in which 

 Antimony may be vitrified.* I only 

 describe the results of my own practical 

 experience, and the first way of prepar- 

 ing Antimony, or glass of Antimony, is 



ic, and you have our true menstruum, whereby the 

 colour is extracted out of glass of Antimony. The 

 tincture of this glass is also extracted by means of its 

 own vinegar, and thence, in this last operation, is ob- 

 tained a most excellent medicine. 



* The curious reader may find such methods in Hart 

 mann, Crollius, Beguinus, and others.
