3D Mushroom Silicone Mould for Resin, Plaster and Cement

A mushroom charm or a small ornament usually starts with a carved master. This silicone mould skips that step: pour epoxy resin, plaster, concrete or cement into the 3D mushroom cavity, let it set, then flex the sides to free the cast. It suits jewellery makers and small-batch craft sellers.

One mould for resin, plaster and cement

✅ Mushroom shape without a carved master The cavity already holds the 3D form, so one pour gives you the mushroom.

✅ Flexes to free the finished cast Silicone walls bend away from the set piece, even round the cap.

✅ Same mould, several casting materials Pour epoxy resin for light charms, plaster for matte pieces or cement for weight.

✅ Built for jewellery-scale pours It is supplied as a jewellery mould, so it suits pendants and earrings.

A session is short: mix a small batch, pour it into the cavity in one steady stream, then tap the mould on the bench so trapped air can rise. Leave the cast to set fully before you touch it, and work the silicone away from the edge first rather than pulling at the stem.

The material you choose changes the result more than the mould does. Epoxy resin takes pigment and stays light, plaster dries to a matte finish that paints well, and cement gives a grey, weighty piece. All three go into the same cavity, so one mould covers the materials you already keep on the shelf.

These casts end up in small places: a mushroom pendant on a cord, a pair of earrings, a charm on a keyring, or a miniature for a shelf or terrarium. Because the piece comes out as a single mushroom, most of the finishing work is trimming the pour line and smoothing the base.
