I got a huge chunk of beeswax from a local beekeeper, and needed to make it ino a size more useful. It was pretty hard, and didn't cut into pieces very well. I bought a couple of flexible plastic ice cube trays at Walmart. Spray the inside if each "hole" with cooking spray, which will act as a mold release agent. Slowly melt wax, and skim off any impurities that may rise to the top. Use a laddle to fill the ice cube trays. Let cool over night, drop out the wax cubes and store in zip lock bags.
