Shaped articles soluble or dispersable in water and liable to give off dust are coated by spraying with an aqueous solution of sodium silicate. If the article is coloured the aqueous solution should also be coloured. Thus, in an example, blocks of household blue (ultramarine, sodium bicarbonate and binder) are sprayed with an aqueous solution of water glass containing Lissamine Violet 10 B.S. The Lissamine may be replaced by ultramarine. Specification 603,148 is referred to.
