Abstract
Glassy coatings are made by curing in situ a coating of a sol gel of tetraethoxysilicon, water and alcohol, filled with kaolinite or with flat plates (1-2 .mu.m.times.10-50 .mu.m) of mica, which may be colored by Fe.sub.2 O.sub.3 /TiO.sub.2 coatings. The coating may be applied to teeth as a dental fissure sealant or varnish to protect restorations, or as an inherently colored cosmetic coating, or as a prophylactic coating.
