Glass
We can use a diamond (or other very hard material) knife glass cutter.
unfortunately the only real chemical name for a diamond is Carbon .. makes this tough to send by mail with £2k insurance!
Such a material is GLASS.
It is usually made from a combination of two or more types of glass, one hard and one soft. The softer layer makes the glass more elastic, so it can flex instead of shatter. Bullet-resistant glass is usually constructed using polycarbonate,thermoplastic, and layers of laminated glass.
You can, but it will shatter when you turn on the burner! We found that out the hard way, twice - just to be sure.
As we know that the glass attracts heat and prohibits heat from escaping from indoors and makes the interior hot . so glass is not a good building material.
Ideally, you don't want regular glass in a garage door, as the door closing hard could shatter them. You would be better off using either tempered glass or plexi-glass.
Not really unless it is destroyed the disk would shatter & the glass shards would be the most dangerous thing
