Basic, tempered glass for high time , will shatter when a cutter breaks the inter part.
Plain glass will not take the direct heat.
Use a tube bread tube, and do not screw with it, adapt it.
oldsanclem Reviewed by oldsanclem on . cutting glass cylinders?? I have found so many vases that would suffice for cool tube glass in asda. All shapes and sizes. My question is how (if you can at all) would you go about cutting the base of these off? They are cheap too, and a cut one would resemble a bake a round. Cheers. Rating: 5
