Okay, so replace "you" with "I" in that last paragraph and that is exactly what happened with this casting project. I wanted to do a quick project using only materials I had left over in the studio and I decided to just improvise the rest.
I did, however, get the 10K achievement for doing every cardinal sin in mold making. A sort of triple crown of failure. And here's how you too can ruin your project, waste materials and add a trophy to the wall you'll want to bang your head on.
Step 1: Use the Wrong Materials
For a successful project, I would have used silicone for something small and highly detailed. So, to ensure failure, I used Dermagel, which is great for life casting since it sets up quickly, is non toxic and easy to use. It is, however, very soft, prone to air bubbles and not durable, making it ruinous for a small detailed projects like this one.
