A friend of mine keeps bees, and asked for help cleaning the beeswax he harvested this year. I figured out a solar oven and filtering setup which melts and cleans the wax. However, I've now got a big chunk of (clean) wax solidified in a plastic bowl, and I'm struggling to get it out!
This was a great trial run, but I'm planning to re-melt this to pour into some ice cube trays, in order to have smaller (easier to use) blocks. How should I prepare the plastic mold so the blocks will release easily? I'll hopefully be using the same technique when we eventually make candles!
