Glass of Antimony, in Latin, Vit••um An∣timonii.
Calcine in a small fire a pound of Antimony in ••owder, in an earthen pot unglazed, stir the mat∣•••• continually with an Iron Spatula, until vapours ••ise no longer; but if notwithstanding your stir∣••••g, the powder should chance to run to lumps, as •• often happens to do; put it into a Mortar and ••owder it, then calcine it again▪ and when it will ••••e no more, and is of a grey colour, put it into good Crucible covered with a tyle, and set it in wind furnace, wherein you must make a very vi∣••ent coal fire round about the Crucible, to the ••d the matter may melt, about an hour afterwards ••cover the Crucible, and put in the end of an I∣••n rod into it, see whether the matter that sticks to is become Diaphanous; if it be, pour it upon a ••arble well warmed, it will congeal, and you'll ••ve the glass of Antimony which you must let cool, ••d so keep it for use.
Virtues. It is of it self the most violent Vomit that made of Antimony.
