Mold Making with Jello

Step 7 The Last Step -- Recycle

Personally, I wouldn't eat the gelatin... But, gelatin has an amazing property - heat it, and it melts. Re chill it and it resets :) You don't get that feature when working with commercial mold making supplies.

This has awesome implications - you can re-use your mold making supply over and over again. Gelatin does have a finite cycle life, but I have yet to hit it (it seems rather high). Just throw it in the microwave on medium power and stir once a minute until completely liquid again - be sure to check for small bits that need a little more time to melt down.

So, if your mold tore apart when you tried to release (at any point).... Melt it down and try again -- perhaps with a little more gelatin powder? Then give it another shot.

What about contaminants?
Oil based mold releases float on top of the gelatin, so when your melt down and refrigerate -- you should have a film of release agent on the top of your solid gelatin -- you can simply wipe it out with a paper towel.

Happy mold making :)

Let me know what you make -- I'm considering casting a plastic soldier or hood ornament just to see how well the gelatin takes to it -- and how the details show up :p

could I make a jello mold and pour jello into it? In other words, I want to make something out of jello but I don't know if it will stick to the jello mold.

Potentially, if there's enough grease to serve as a mold release... I tried, and failed :/ But if there isn't, you're essentially jello welding :p
