Frequently Asked Questions

Each kit includes the materials listed on its product page — typically pre-measured gypsum, natural stone or glass aggregate, a reusable silicone mould where specified, an illustrated step card and a sanding sheet. Pigments and sealers are sold separately unless the product page says otherwise.

No. Our kits are designed for beginners. You mix, pour and demould; the illustrated card walks you through each step. Demoulding usually takes about 15 minutes, and the piece is fully cured in about 2 hours.

Gypsum and stone aggregates are low-toxicity craft materials. Mix in a ventilated area, wear a dust mask and gloves, and keep powders away from children and pets. Cured pieces are decorative; they are not food-safe unless you seal them with a food-safe sealer.

Each product page states its coverage (for example, “makes 2 discs, 20 cm diameter”). The mould is reusable, but the gypsum and aggregate included in the kit are measured for the stated coverage.

Every piece is cast by hand from natural stone and recycled glass, so grain, colour and texture vary slightly. Swatches and photos are a guide, not an exact match. Order a free sample kit to compare colours at home.
