Casting resin in non traditional plastic molds

Casting resin in non traditional plastic moldsCasting resin in non-traditional plastic molds

As a part of my year of doing resin experiments, I took on the task this week to see whether or not I could cast resin in a gelatin mold.  Even I was surprised at the results!

A couple of key points in the video:

1.   You must use a mold release.  I like the Petrolease mold release for helping me to get difficult castings out of the mold.

2.  If you are going to use the Petrolease mold release, a couple of light coats is plenty.  Do not saturate your mold.

3.  Once you use a food mold for resin (I used a gelatin mold in this video), do not use it for food again.

4.  Be prepared to ruin the mold.  Your resin may not demold, you may melt the mold, and who knows what else.  Know that you may have to trash everything!

If you are wondering about the supplies used in the video, here are links to get more information:

Great tutorial and I love how the pieces come out!
“3. Once you use a food mold for resin (I used a gelatin mold in this video), do not use it for resin again.” I think you want to say “do not use it for food again” 🙂

I use this mold and I just put the mold in the freezer for a few minutes and the resin pieces just pop right out . Love it !

Hi, Katherine, I am a looong-time Sci-fi fan and love the way the Star Wars figures came out! It had my fingers itching to get out my paints!

I think it’s amazing all the different things you can do with plastic molding. I think my niece and nephew would love these little moldings you did! Especially because the movie just came out; they absolutely loved it. We will have to try this with them. Thanks for the great idea!

I wanted to make resin legs for a wood/resin nightstand top I made. .I like the shape of the 1 litter Sprite bottles for this, do you think I could let my resin cure in the bottles then simply cut my makeshift mold away after it does? I tried some reusable lasted bowls that shredded cheese came in and they worked super but I need something make more of a curvy leg shape for this project. any thoughts?
