Abstract
Heat-resistant masking compositions suitable for use in masking vitreous and semicrystalline ceramic surfaces from coating by liquid-sprayed coating compositions to provide permeation-resistant masks which are readily removable even after high temperature firing are described. The masking compositions comprise bentonite clay and a finely-divided refractory inorganic oxide release agent.
