If lead is exposed to the vapours of warm vinegar, it is corroded into a kind of calx, which is used in oreat quantities in painting, and is known by the name 5f Ceruse or White-lead. The preparation of this pigment, has become a distinct trade, and is practised in some places of this kingdom, where leadds procura- ble at the lowest price. The process for making White-lead is as follows. Leaden plates rolled spirally, so that the space of an inch shall be left, between each circumvolution, must be placed vertically in earthen pots of a proper size, containing some good vinegar. These leaden ro s ouaht to be so supported in the pots, that they do not touch the vinegar, but that the acid vapour may cir- culate freely, between the circumvolutions. The pots are 10 be covered, and placed in a bed of dung, or sand bath, by which a gentle heat may be applied. T he acid of vinegar being thus reduced into vapour, easily attaches itself to the surface of these plates, penetrates them, and is impregnated with the metal, which it re- duces to a beautiful white powder, called Ceruse. When a sufficient quantity of it is collected on the plates, the rolls are taken out of the pots and unfolded; the Ceruse is then taken off, and they are again rolled up, that the operation may be repeated. . , In this process the acid being overcharged with
