  • Silicate coating for heat-resistant objects, said coating having a heat transfer function; objects having said coating; and process for producing such a coating
    Patent number: 4361622
    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.
