PURPOSE: To apply a transparent ornament of uniform and clear colors on the surface of a rugged body or on the inner surface of a transparent vessel.

CONSTITUTION: Titanium tetrachloride and glycerol are thermally condensed to synthesize a water-soluble titanium ester, tin chloride is dissolved in 2:1 to 1:9 molar ratio of Ti/Sn, and pure water is added to obtain the aq. dil. soln. A body with the surface cleaned is dipped in the dil. soln. which is boiled to deposit the hydrolyzate on the surface, and the surface is coated with a film of the mixture of titanium dioxide and tin oxide. Alternatively, a soln. contg. tiatnium and tin is applied on the body surface and baked to obtain the oxide coating film. The surface is pretreated in this way. The body is then heated in a film forming soln. prepared by adding a minute amt. of polycarboxylic acids to an aq. soln. of titanium tetrachloride acidified with hydrochloric acid, and the formed titanium dioxide is deposited on the pretreated surface.
