Acetic Acid, commonly called Distilled Vinegar. Sublimates are chemical preparations, the basis of which is quicksilver. In corrosive sublimates, the quicksilver is extinguished, either by vitriol, potter’s clay, or some other ingredient. Sublimation is a similar process to distillation; only solids (such as metals) are employed, instead of liquids. Thus the fine blue used by painters is a sublimate, and made thus:—Take 2 parts of quicksilver, 3 flower of brimstone, 8 sal ammoniac; and (having ground them) put them with the quicksilver into a glass retort, luted at the bottom; place the retort in a sand-heat; and (when the moisture is given off) you will have a splendid blue sublimate for painting. |
