Silicone Sphere Mould

A silicone sphere mould is a versatile tool essential for effortlessly casting perfect resin spheres, making it popular among jewellery makers and decorative craft enthusiasts.

Why Choose a Silicone Sphere Mould?

Silicone sphere moulds stand out for their flexibility, smooth finish and ease of use. Their non-stick surfaces promote easy demoulding, leaving your cast spheres with a polished result, ideal for resin, soaps, wax and more. With a range of sizes typically included in one mould—such as 1 cm, 1.5 cm and 2.5 cm diameters—you can tailor your crafts to suit earrings, pendants, keyrings, and decorative projects.

Using and Caring for Your Sphere Mould

Before pouring resin, ensure your mould is clean and dry. Mix your resin carefully to minimise bubbles, then fill each cavity slowly. Once poured, allow sufficient curing time but take care not to leave resin in the mould for more than 12 hours, which helps prevent sticking. After demoulding, wash the mould gently in warm, soapy water and avoid harsh solvents. With proper care, your silicone mould remains reusable and maintains its polished finish for many casting sessions.

If you wish to start straightaway, the “3 Sphere” – Silicone Mould for Jewellery and Crafts, 1cm-2.5cm Spheres offers three convenient cavity sizes, semi-transparent silicone for easy monitoring, and excellent durability.
