Abstract
A spray glaze or opaque composition for coating dental restorations and other surfaces and objects such as hobby ceramics that comprises about 4 to about 50 weight % glaze material, about 5 to about 60 weight % restoration wetting agent, and about 10 to about 90% non CFC propellant. An opaque composition further comprises about 5 to about 30% opaque material.
Claims32
A method of preparing a dental restoration, comprising:
- providing a dental restoration
- providing a canned aerosolized spray opaque composition that comprises opaque material;
- a wetting agent, and a non-CFC propellant;
- providing an aerosolized spray glaze composition that comprises glass frit;
- a wetting agent;
- and a non-CFC propellant the spray glaze comprising about 4% to about 50% glass frit, about 10% to about 80% wetting agent, and about 10% to about 90% non-CFC propellant;
- spraying the aerosolized spray opaque composition onto the dental restoration to provide an opaque coating;
- firing the dental restoration to set the opaque coating;
- building a porcelain restoration body over the opaque coating to provide a porcelain restoration;
- firing the porcelain restoration;
- grinding the porcelain restoration body to resemble a human tooth restoration;
- spraying the aerosolized spray glaze composition onto the ground porcelain body to form a glazed restoration;
- and
- firing the glazed restoration to set the glaze.
