What is annealed Glass?

As mentioned above in how is glass made, annealed glass is how glass is born, glass at it’s most basic level. It is the most familiar. Annealed is the glass that shatters when you have to bust through it to escape the bad guys. In fact one of the sharp and very dangerous shards, when carefully placed, may fall with impeccable timing on said bad guys. Spoiler alert, movie glass is made from sugar. Annealed is the weakest type of glass and also very dangerous. Thickness can help a little with strength, but not safety.
