Can someone help me for using forced propane burner as my heating element. I rather want to use lpg than electric. Do you think it would work

Glass and metal heat compatibility
carelgrundlingh
First off....HAPPY NEW YEAR greenman

I will be using stainless steel and glass for my RC. My glass cylinder fits inside my stainless steel base (cocktail shaker) and top (stainless steel cup).

How tight can the fit be without worrying about heat expansion? Does glass expand at a slower rate than stainless steel, and will the glass not be compromised (read: shattered) when the stainless steel shrink back when cooling down to room temperature, if the glass fitted snugly at the start?

Thanks for helping out!

It depends what type of glass you are using. The proper glass (borosilicate, or pyrex) has a very low expansion, which is why you can use it at high temps. You would not need to worry about when it cools, as long as it fits cold. You need to worry about when the metal expands as it gets hot. I doubt that the stainless shaker would expand enough to break your glass, even if it was snug.
