Melt glass in Microwave

I found this interesting instructables:


considering the small size of the microwave, this may be a bad idea…

What does size matter here? I mean, I can imagine all sorts of fun ways for things to go wrong, but the size of the microwave doesn’t factor in to them. :slight_smile:

to take in and out the ceramic pot thru the small opening may be difficult.
the closeness of the heating element (microwave radiators) to the liquid surface may cause impurities to evaporate and react with the radiators

What liquid surface?

And… it has been actually working, so theoretical problems haven’t materialized for him.

molten glass despite high viscousity could be considered liquid…but good that he didnt have any problems
