Abstract
Soluble glass, obtained as usual from quartz sand and an alkali salt, is dissolved under heat and pressure to give a solution of say 50 per cent strength and the latter evaporated, for instance on a cylinder drier, to give a solid silicate soluble in water at ordinary temperatures. By introducing a pigment into the solution to be evaporated, a solid silicate colour readily soluble in water to give a silicate paint is obtained.
