This is the time of year you will be able to find some interesting ice cube trays. I love this one! You might be surprised that you can use them as a mold to cast wonderful resin pieces. Once you do however, do not use them for ice or food making.
I whipped up two batches of EasyCast resin for this ice cube tray experiment. To one batch I added white pigment and to the second black pigment. These pigments are opaque, so the molded item will be solid colour.
I'll show you how they look after they cure for the next 24 hours!
