Abstract
Glassy coatings are made by curing in situ a coating of a sol gel of boron triethoxide, water, alcohol, and the alkoxides of: titanium and zirconium. A platey filler such as mica is present. The coating may be applied to teeth as a dental fissure sealant or varnish to protect restorations, or as an inherently coloured cosmetic coating, or as a prophylactic coating.
