The easiest way to remove votives or tarts from their holders is buy filling your sink or basin with aboiut a half to an inch of hot water, set holder into water for a few min. and the will readly pop out with a bump of a butter knife. If you tart burner is all one piece, light you tea light, give it a min or two and it will be easily removed. Be sure to use a paper towel as the very bottom may be hot. This works on Jar candles as well. I remove the remain wax, and recycle it in my tart burners. No waste here.
