The ability of a material to emit radiant energy. Emittance is the ratio of the total radiant energy emitted by a given surface to that emitted by an ideal black body at the same temperature. To emit is to give out, to discharge—in the case of glass, essentially, to re-radiate absorbed energy (heat).

Heat-strengthened glass is approximately two times as strong as annealed glass of the same thickness and has a much increased thermal endurance. Heat-strengthened glass is approximately two times as strong as annealed glass of the same thickness and has a much increased thermal endurance. Heat-strengthened glass is considered a safety glass and will not completely dice as will fully tempered glass.
