Casting Resin Crystals

[darth_chasm]

I picked up some silicone mold rubber and resin to make molds of and cast some crystals. Cool thing is, I ordered same day shipping from Amazon and the package didn't arrive on time so they gave me a full refund and told me to keep the products

Never done this before and I'm not sure if I mixed the compounds thoroughly enough, so it may not turn out too well. I'll update later tonight when the silicone has hopefully fully cured.

I am going to try to add some coloring to the resin to get different ones. Possibly even cast one in a color, break it into pieces and then throw those pieces into a clear cast. In my mind that may create a pretty cool effect.

Here's what I'm using and a pic of the mold degassing/curing. Wish I got some pics of the crystal beforehand but I was too anxious to get started. I just hot glued it to the bottom of the cup.

That really looks like fun! I like the idea of using a mold to make crystals. I did a few test runs of making crystals by using crushed calcite crystals mixed in with tinted epoxy. If you are going to tint epoxy do some tests outside of the mold first. It's super easy to make your crystal opaque by adding too much tint. Really interested how yours turns out. Will you have to cut your mold in half to remove the original crystal?

Yeah, you're supposed to cut it out. Probably not all the way in half though. From what I've read and seen, you cut it down the sides in a zig zag fashion so the mold keys up better. Then I just throw it back into the cup to hold the position. Apparently, the blob of hot glue creates a nice mouth to easily pour the resin.

I'm interested in how this turns out for you as well. I have a couple crystals that I'd like to try casting. One looks like it could almost be from the caves on Illum.

The mold cured so that's a good thing. I put a cut off cup and s piece of tape around it the hold it in place. Then mixed up the resin and poured. I am a little worried about the resin as that has a ton of bubbles in it some are popping but I'm sure a lot will be left over. Now the waiting game. The resin takes 18-24 hours to cure :/

The waiting game sucks. Let's play hungry hippos.
