Shirlee, you can use the wax for yourself. I used c-3 soy as my wax for my tarts when I first started, Yes they were hard to get out of the mold, I popped them in the freezer for a few minutes, I just finally switched wax cause I was tired of the messy packaging it was leaving. I still have like 20 lbs that I intend to use for my own tarts one of these days. Im not sure why you think soy is usless for tarts.
