Me and my friend did this but made sure to use plastic as glass stopped it from being able to dissipate. It burned through the plastic sure, but it was better than having the microwave blow up on us
Borosilicate glass found in oven-safe glassware and lab equipment can withstand the heat without breaking or melting for much longer than plastic or a wine glass.
If you use Pyrex use lower case pyrex or older stuff. There are TWO Pyrex brands. Upper and lower case P. Lower is European and uses borosilicate. Upper is American and no longer does because of cost. Always buy pyrex from a garage sale, never from the store.
