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.
