How To Make your Own Silicone Mold For Polymer Clay

January 27, 2020 by Shellie Wilson

Start by mixing the two ingredients together.

Silicone and cornstarch

You need the paste to be the consistency of a dough. It shouldn’t stick to your fingers and should come together. Once you are able to roll it into a ball it is the right consistency.

Shape your ball into a rectangle or square a 1/2 inch thick (depending on the depth of the item you are casting)

Then simply push your casting item (shell) into the dough.  If you are not happy with the impressions just roll it back into a ball and start again.

It will take 2-3 days, depending on the weather to dry.

Use this mold to press your polymer clay into. You may need  a mold release such as oil to remove the polymer clay shape once it has been molded. Then press out and bake as per the usual polymer clay instructions.

    This is brilliant! I’m a dental hygienist and I have used dental impression materials for my molds. This would be so much easier and less expensive!

Book Review Wednesday: Air-Dry Clay Making Handbook

This week’s Book Review Wednesday pick is Air-Dry Clay Making Handbook by Jacalyn K. Myron, and this is another one of those crossover craft books that could easily live in more than one corner of CraftGossip.

It is not strictly a jewelry making book, but the cover does mention jewelry projects, and air-dry clay is a lovely material for making lightweight pendants, charms, ring dishes, earrings, beads, and little decorative pieces. So I’m letting it sneak into the Jewelry Making series because, honestly, half the fun of handmade jewelry is experimenting with materials that were not necessarily “jewelry supplies” to begin with.

Air-dry clay is especially appealing for beginners because you do not need an oven, kiln, torch, or specialist setup. You can shape it, texture it, let it dry, sand it, paint it, seal it, and turn it into something sweet and useful. It is very approachable, which makes it a nice option for crafters who want to try clay jewelry without jumping straight into polymer clay baking or resin mixing.

This book looks like a practical beginner guide covering air-dry clay techniques, tools, tips, and projects, including jewelry, home décor, animals, figurines, and small sculptures. I like that mix because it gives makers room to play. You might start with a simple ring dish or pendant and then wander off into little bowls, ornaments, charms, or handmade gifts.

For jewelry makers, I’d see this as a gentle introduction to clay-based accessories. Think handmade pendants, textured earrings, little clay charms, or small dishes for storing rings and earrings. It would also pair nicely with our Jewelry Making projects and the more clay-focused ideas here.

My Shellie-style take? Air-Dry Clay Making Handbook looks like a calm, beginner-friendly craft book for anyone who wants to try clay without too much fuss. It may lean more general craft than pure jewelry, but there is enough jewelry potential here to make it useful for makers who enjoy handmade accessories, gift projects, and pretty little things made by hand.

You can find the book here: Air-Dry Clay Making Handbook.
