How can I draw from melt wax that have re-solidified out of cup jar? Is it safe to microwave them, or should I put them...

Is it safe to microwave them, or should I put them surrounded by a dish of warm dampen? OR...?
Answers:    put the jars contained by the freezer for about an hour, later gently hit the wax out.
or grab a axe and stick it into the center of the wax, then verbs the knife around and erect up. after that, pour hot water into the jar, consent to it sit a couple minutes, then dump the hose and wipe clean! i used to waitress and i'd own to change the candles every time. this is how we did it.
I would put them in a tub of really hot water, consequently remove them after a few minutes and wipe them out with a thesis towel.
