Imagine my joy when I opened a box of cereal for my peeps a couple of weeks ago to find a mold.  I get it was intended to freeze water or juice, and not end up on my resin crafting table, but I found it first.  I couldn’t possibly pass on the opportunity to try resin casting in a ‘new to me’ mold, especially if that mold was not intended for resin.

Here’s what is different

This mold is very stiff, even stiffer than I find most ice cube trays.  Knowing that demolding was going to be a challenge, I prepped it with a light layer of my favorite resin mold release.  This is my go-to mold release, especially for those hard to demold projects.  I grabbed some Resin Obsession super clear resin and colored it with transparent purple pigment.

One-half ounce of mixed resin is all that was necessary to fill the mold.  I let it fully cure before demolding.

Surprises with resin demolding

I prepared myself for needing to pop this in the freezer and slap it on the countertop in order to get the resin out.  Imagine my surprise when I started pushing from the back and heard the resin crack like an ice cube.

{{ Of course, I should have known this was going to happen.  As soon as I announced on video that this isn’t going to work and I’m going to need to freeze it and go all-ninja, of course that would not need to happen.  The resin always wins. }}

The casting didn’t break during the demolding and quite frankly, turned out better than I expected.

The octopus came through with great details and a beautiful transparent purple color.  His surface is frosted from the surface of the mold.  At this point, I could use a couple of light layers of resin gloss sealer spray to get him shiny.

  1. I love the purple, and think the matte finish is gorgeous! I would use it for a pendant with purple fishy or starfish earrings.

  2. Awesome idea! I’ve been thinking of trying the same thing with some cool ice cube molds I have, but I’ve been a bit concerned about whether or not it would be safe to reuse the molds for ice afterward. Any thoughts on the matter?
