My step mom gave me shells from my dad after he passed. I wanted to make a resin “rock” with the shells but I’m not sure what type of mold/resin to use. Some of the shells are pretty big so I was thinking a bowl of sorts so it could sit flat. After reading the glass comments, glass is not the way to go. I believe the resin needs to cure a bit (30%) before adding shells? The large shells in last. The mold is my biggest stumper. Any ideas are greatly appreciated. Thank you!

Hi Susan,

Yes, you’re going to need a mold for your project. Unfortunately, we don’t have anything like this in our store.

Once you get the mold, you’ll need to know how much it holds so you know which resin to use.

Since you’re working in molds, you need to use a resin designed for those. We’ve got two. The one you use comes down to how much resin you’re mixing and pouring at once.

For pours of 3 ounces or less, the Resin Obsession super clear resin is what you want: https://shop.resinobsession.com/collections/resin/resin-obsession-super-clear-resin
For pours of 3 ounces or more, the Resin obsession deep pour casting resin works great: https://shop.resinobsession.com/collections/resin/resin-obsession-deep-pour-resin

If you need help figuring out how much resin you need, our free resin calculator can do it for you: https://www.resinobsession.com/resin-calculator/

You’ll need to put the shells in while the resin is still liquid. Otherwise, you’ll introduce bubbles that likely won’t come out before it begins curing.

If you can’t find a bowl mold, here’s an article showing how to put shells in a resin business cardholder: https://www.resinobsession.com/resin-tutorials/diy-business-card-holder/
