Will glass break if i heat it?

Question

Will glass break if i heat it?

Answer 1

I think It will melt if you heat it a lot. But I don't think it will break if you put it in the microwave

Answer 2

You can heat any glass without breaking it until it gets so hot that it melts.  But, if you heat it very quickly (just as if you cool it quickly), or if you heat it unevenly such as by applying a flame to a spot on it,, then it will break quite easily.    If it has small and perhaps invisible cracks or stresses already in it, that helps it break by quick or uneven heating.  

The bit with Pyrex, uh nope..  it's a better and more crack resistant glass, not just against heating.  It melts at higher temperature than common glass and doesn't expand as much.   The breaking due to heating is from thermal expansion.  Heating slowly and evenly helps to keep one part of the glass from breaking away from another part of it due to uneven expansion.  Remember, glass is also an insulator so it takes time for heat to distribute evenly within it.

Answer 3

yes because it absorbs the heat. would u break if u get trapped into an oven at 600 degrees? same logic.

Answer 4

no i think it will just melt

Answer 5

It explodes then it melts

Answer 6

If you heat it then instantly cool it, it will shatter.

Answer 7

If you cool it instantly it will explode.So be careful.

Answer 8

yea

Answer 9

Depending on the structure of the glass, yes.

Pure glass will shatter at extremely high temperature due to the change in it's molecular arrangement. Pyrex and other glass-composed material will be damaged at much lower temperature, because of the impurities contained in the material.

The important thing to remember is to let a cooldown time after exposing glass to extreme temperature. Exposing a super heated Erlenmeyer to cold is a sure recipe to shattering.

Answer 10

yes it will but  it has to be a glass of water put in a microwave and heat it up hot it will breaka dn watwer will explode ps never put alumin um foil in microwave big firee

Answer 11

Boy, are there a lot of wrong answers here.  Especially the one that mentions the impurities in Pyrex.  

You can heat up any sort of glass and it'll melt without shattering if you do it right.  Since Pyrex doesn't expand with heat it'll melt without too much trouble, but you'll probably have better luck with a soft glass.  The trick is to apply the heat evenly so that the temperature in all parts of the piece you're heating stays about the same.  

For Pyrex you need a fairly aggressive heat source: something with oxygen in it, or at least compressed air.  But soft glass--like neon sign people use--can be melted on the flame of a gas stove.  It's fun.  

Answer 12

At a certain degree, yes.  But not in a microwave, prolly.  An oven, yes, maybe.  If you heat it really REALLY slowly, you can blow it and make yourself something nice.  Like a bottle or another bowl perhaps!

Answer 13

nop.

Answer 14

It will melt. But it will break it you cool it suddenly after it is hot.
