The objective of this proposal is to develop an environmentally benign, novel re-manufacturing process to relief the bothersome scratchitti vandalism- permanent scratches on the glass surface. In this proposal, an innovative approach, controlled fire polishing, will be used. Intensive heat melts only a thin layer of the glass panel. During the cooling process, the surface tension will even out the scratching indent. The process will enable the reuse of the damaged window/door and eliminate the otherwise waste by replacement new glass. It allows a better living environment for people, rid of the unpleasant and annoying graffiti vandalism.
