Have you ever wanted to make a mold and cast something -- but were discouraged by the cost of casting supplies? Have you ever just wanted to make one duplicate -- rather and one thousand? Perhaps you only wanted to make one or two chocolate book marks or plaster casts of an ink jet cartridge...
Well, here's a very DIY, cheap an recyclable method to make molds for relatively low temperature casting.
Step 1: Materials
You will absolutely need:
Gelatin -- I'm using Jello
A vessel to pour in that will hold your positive item
A refrigerator with space for your vessel
You may need:
Skewers or other support device
You probably want:
Chap Stick or Vaseline (chap stick being "edible")
