A process for the reuse of waste glass at relatively low temperatures to create commercial glass products. The steps of the process include filling a tray with waste glass, placing the tray inside a kiln, heating the kiln to a sequence of stages, each stage having a designated temperature and a designated time interval, the stages including initial heating, soaking, annealing and then reducing the temperature to reach ambient temperature. The tray is then withdrawn and a glass block is taken out of the tray. The glass block is then precision cut to create a commercial glass product.

In a method of making shaped glass articles, a glass sheet is placed on a mold having a shaping surface with a desired surface profile of a shaped glass article. The glass sheet is preferentially and rapidly heated by radiation while in the vicinity of the mold so that the mold remains substantially cooler than the glass sheet during the heating. The glass sheet is sagged onto the shaping surface of the mold so that at least a portion of the sagged sheet assumes the desired surface profile of the shaped glass article. After sagging and shaping, the sagged and shaped glass sheet is removed from the mold.

A process for producing a glass substrate includes a step of forming an antiglare region on at least one of main surfaces of a glass plate, a cutting step of cutting the glass plate and a removal step of removing a part of the antiglare region.
