Heat-strengthened Glass
Heat-strengthened glass is glass that has been heat treated to induce surface compression, but not to the extent of causing it to "dice" on breaking in the manner of tempered glass. On breaking, heat-strengthened glass breaks into sharp pieces that are typically somewhat smaller than those found on breaking annealed glass, and is intermediate in strength between annealed and toughened glasses.

Famous quotes containing the word glass:
“Thou didst create the night, but I made the lamp.
Thou didst create clay, but I made the cup.
Thou didst create the deserts, mountains and forests,
I produced the orchards, gardens and groves.
It is I who made the glass out of stone,
And it is I who turn a poison into an antidote.”
—Muhammad, Sir Iqbal (1873–1938)
