Make your own Wax Tarts

I get frustrated when I burn candles & all the wax doesn't burn.  I found two ways to deal with this & to continue enjoying them.

I have a hot plate that I used at work to keep my tea hot that I can put the jar on to melt the wax.  If there's a lot of wax I keep doing this to release the smell.

The other thing I've found is to use an empty plastic tart holder & refill it with the melted wax.  Then I can break off whatever I want & put it in my tart warmer.
