Abstract
A silicate coating for heat-resistant objects, particularly containers having a heat transfer function, e.g. cooking pots or baking pans, is disclosed. The coating solves the problem of improving the heat transfer and heat distribution while at the same time improving the appearance. Toward these ends, it is proposed that the coating contain at least 10 wt. % of a mica, and be fired or baked on the object at a temperature below the decomposition, melting or dissolving temperature of the mica.
Claims10
A heat resistant object having a coating on a surface thereof for improving the heat transfer properties of said surface, said coating consisting essentially of an inorganic silicate mixture containing at least 10% by weight of mica baked on said surface at a temperature below the decomposition, melting or dissolving temperature of said mica, wherein said mica is modified with titanium dioxide.
A heat resistant object having a coating on a surface thereof for improving the heat transfer properties of said surface, said coating consisting essentially of an inorganic silicate mixture containing at least 10% by weight of mica baked on said surface at a temperature below the decomposition, melting or dissolving temperature of said mica, said mica being applied to the surface of said coating prior to any baking process.
