Abstract

Lakes are made by liberating, in a mass of china clay, alumina and/or silica and combining the product with acid or basic aniline colouring matters, according as alumina or silica predominates. After treatment with acid sulphate of soda solution, sodium carbonate solution is added to precipitate alumina. The paste is filtered and the residue, after washing, treated with sulphides of sodium and heated to boiling point with a solution of colouring matter. To obtain siliceous blues the product of the acid sulphate reaction is extracted with water to remove the aluminium sulphate and the residue treated with carbonate as before.
