Powder, Wash′ing. The numerous compounds vended under this name have for their basis the soda-ash of commerce, blended with common Scotch soda in variable proportions. The best of them consist either wholly or chiefly of the first of these substances. The alkaline matter is reduced to coarse powder, and stirred up with liquid size, or with a decoction of linseed, Irish moss, or British gum, and is then dried, and again crushed or powdered, and at once put into the packages, in which it is rammed tight, and covered up immediately. The object aimed at by the manufacturer is to keep his commodity from the air as much as possible, because exposure renders it less caustic, and consequently less detergent.

Powder of Yellow Bladder-wrack. (Ph. D.) Syn. Pulvis quercus marinæ. Prep. Yellow bladder-wrack, in flower, is dried, cleansed, and heated in a crucible with a perforated lid till vapours cease to be given off, and the carbonaceous residue reduced to powder.—Dose, 10 gr. to 2 dr.
