No. Glass tempering is a physical strengthening process that does not alter the glass’s density or thickness, so there is nearly no difference in weight. The superior strength of tempered glass over regular glass stems from pre-stress formed inside the glass, rather than added material.

Printing must be completed prior to tempering. Ceramic ink for glass requires sintering at high temperatures (usually over 600°C) inside the tempering furnace to achieve permanent curing, resulting in a hard, wear-resistant and corrosion-resistant finish. Therefore, the printing procedure must be finished before glass tempering, and the tempering process doubles as the ink sintering process.
