Prepare the black resin layer. It takes 2 parts resin to 1 part hardener. Use the measuring cups to measure and mix in a separate disposable container. Here we used 10 ml of resin to 5 ml of hardener which we will use for another project and for our testers so we don't waste. Add a few drops of colorant. 2 or 3 should be enough.
For the testers, take small containers that you will throw away later so you can test the hardness of the resin as you go. For example, you can use bottle caps.
