[Stoves] Glass stove parts

[Jigme Rangdrol]

Greetings Frank.
You will have to get someone else to explain the expansion coefficient 
function but yes it is expansion per degree Celsius. The high and low 
are the range of expansion.
The main thing with this stuff is it claims to be extremely stable with 
almost no expansion.
It is made with a heating cooling cycle that produces a crystal 
structure - or so I understand anyway.
I would like to find out what the mix is.
That makes it much harder for glass making on the cheap but its 
outstanding shock resistance and low EC makes it a target.
The demo I saw shows a blow torch heating the glass red hot and pouring 
water on it with no effect.
