Abstract
Coating and filler materials for localized thermal processing of glazed ceramics and other brittle and low thermal conductivity materials. The coating materials include oxide compositions that exhibit coefficients of thermal expansion which are less than about 8×10−6/° C. and glass transition temperatures which are less than about 400° C. The filler materials include particulate oxide materials which do not substantially react during localized thermal processing of glazed ceramics and other brittle and low thermal conductivity materials. The coating and filler materials are useable together as a composite material for repairing cavities having depths greater than about 2 mm.
