Can you use clay as a mold for resin?

Yes, you can use epoxy resin over baked polymer clay to seal it, strengthen it and give it a gorgeous, glossy, look. To cover polymer clay with ArtResin, paint it on with a disposable foam brush or apply it with gloved hands.

Take equal parts white stuff and yellow stuff from the tubes. Mix it together very well. Roll the clay into a ball and start to flatten out. Mold around your item, pushing into air pockets and folds as needed to get an exact duplicate.

If you are making a mold and need to use clay for an original model or creating mold walls, your best bet is to use non-sulfur based clay. There are several non-sulfur based clays to choose from.

Why use Polymer Clay for making molds? … It’s very durable because when cured the polymers inside fuse together making a kind of plastic. You can bake it in a home oven unlike most traditional clays. You can make molds from it in all kinds of materials (including silicone) without using a mould release.

You can use epoxy resin to coat thoroughly-dry air-dry clay and make it waterproof, but it won’t be *totally* food safe, especially perhaps for acidic foods and hot foods (similar to polyurethane).

We recommend using melamine, medium density fibreboard (MDF), or smooth plywood for the base and walls. If you are wondering about other materials for your mold surface, see below for a list of materials that epoxy will and will not stick to.

The acidity of the vinegar breaks down the clay a bit, and makes it sticky. Some artists use vinegar straight from the bottle, or add vinegar to clay instead of water to make a joining slip. All these methods work to create a join that is stronger than water or slip alone.

Because some materials like varnishes, paints, and glues can be softened by the plasticizers in polymer clay, compatibility with polymer clay is a common concern for clayers. Rest assured, both UV and epoxy resin work perfectly well on cured polymer clay. There are no short or long term interactions.

Polymer clay also won’t shrink while it is hardening, unlike air dry clay. Another important difference is that polymer clay is known to be more durable than air dry clay after baking. Once polymer clay is baked, it is waterproof and long-lasting. Meanwhile, air dry clay has the tendency to dissolve in heat or water.

Varnish or acrylic sealers. If you want to make your clay water-resistant I always recommend using either a clear polyurethane varnish or an acrylic sealer. Both of these create a non-porous transparent layer that seals your clay project.

Resin art uses epoxy resin which is synthetically produced to mimic the desirable properties of natural resin. Epoxy resin consists of a two-part system of synthetic polymer resin and a hardener. Once these components are combined, they undergo a chemical reaction which hardens the mixture to form a solid medium.

There are several ways to seal air-dry clay. The easiest way is using varnish or acrylic sealer. For a more robust seal, you can also use liquid epoxy. All of these sealers will make the clay water-resistant and protect the color underneath if the clay is painted.

One thing to keep in mind is if a mold is made of silicone you can use it for resin! Which means baking molds are fare game… just be aware that most resin molds are glossy (which leaves your piece with a glossy shine to the front!) whereas baking molds often leave your piece matte.

Put your resin object in the sun if you don’t have a UV lamp. If you don’t want to bother with a UV lamp, you can simply set your resin object outside in the sun to cure. However, be aware that this could take longer or be less effective if you live in an area with a low UV index or the weather is overcast.

This resin can be pigmented with translucent or opaque pigments if desired. Clear cast cures with a surface tack which will cross link with any subsequent layers that may be cast (poured). … These containers do not need any release agent, as the resin does not stick to food grade plastic containers such as Tupperware.

Here are a few well-known materials that epoxy resin doesn’t stick to: Parchment or Wax Paper. Sheathing or Tuck Tape. Silicone, Vinyl or Rubber.

1. Step 1: Select your silicone mold. Silicone molds are great for casting resin. …
2. Step 2: Apply mold release. Spray a light mist of resin mold release to the mold. …
3. Step 3: Mix and pour resin. …
4. Step 4: Remove bubbles. …
5. Step 5: Let cure. …
6. Step 6: Demold the cured resin. …
7. Step 7: Wash your mold.

The use of sand to improve the strength of natural clays provides a viable alternative for civil infrastructure construction involving earthwork.

Paper Clay is a mixture of clay and paper fibers. Using it you can attach wet and dry pieces, and they will not crack. There are several excellent books on Paper Clay. … A final technique for encouraging good attachment of wet and dry clay is to wrap wet newspaper around the completed object, then wrap in plastic.

Below, clay is used to seal the exterior edges of a mold box that’s being used to make a two-part baluster mold. Plasticine clay can also be used to the seal the edges of mold shells.

Epoxy is a self-hardening clay. Like liquid resin, two parts are mixed together, beginning a chemical reaction. Over a 24 hour period the clay hardens. No kiln needed, no oven required.

2) Epoxy clays, which cure rather than dry, as a result of a chemical reaction. They are usually sold in two parts that are mixed together.

It is safe and waterproof with 0% shrinkage/cracking! Working time is 2-3 hrs. Cures hard in 24 hrs., and has a semi-gloss finish. Adheres to plastic, resin kits, wood, metal, ceramic, glass, polymers, foam, fiberglass, & more!

Since air dry clay isn’t fired, you won’t be using any glaze. … Just as with regular clay, encourage your students to experiment with different ways to add color.

Your best bet -to avoid yellowing in the future- is an artist-grade sealant or water-based varnish. You can also use watered-down PVA glue or Mod Podge (which is basically the same thing). I use polyurethane water-based varnish (Varethane) for polymer clay and it works just as well for air dry clays.
