The idea was a gift for my niece who is addicted to chocolate. It was a great way to teach her about mold-making & casting, as well as sharing! (we made party favors)
You will need:
- Acrylic, size to your specifications
- Equinox Silicone Putty (I used Equinox 38)
- (Optional) Hot Glue
- Access to laser cutter
- 2 pots
- Stove Top
- (Optional) Hot Glue Gun
Step 1: Design and Make your engraving
Alternatively you could use wood. I like acrylic because it is clean after being etched and doesn't need any additional modifications such as sealing. Also, I would NOT recommend using masonite or similar material that can be cut with a laser if particles might find their way into your mold.
If you are interested casting multiple piece at once, I recommend designing a gang mold at this stage.
Obviously this form is modeled after a Hershey's bar. If you are interested in making a grid of pieces that can be broken up, design your illustration for the form accordingly.
