Can you convert old candle glasses in to shot glasses?

Question

I have these pretty little glass candles I have already burned down, and there is still wax in them. I wanted to know if first it was safe?, then what is a safe way to remove all the wax?

Answer 1

get the wax out by putting it in the microwave and yes they would b safe for shot glasses

Answer 2

Freeze them and take a table knife and pop the remaining candle wax out. Then run them through the dishwasher and it will clean them up, or soak them in a sink of very hot soapy water.

The are just glasses, like you drink out of except a cheaper quality. There is nothing unsafe about them.
