How to choose resin, moulding and sculpture supplies

Choose materials by the finish and detail you need: silicone moulds capture fine detail and release easily, plaster is economical for larger casts, and resin gives a glassy, durable piece. Check which casting materials each mould is compatible with.

• Platinum-cure silicone is generally more durable; tin-cure silicone is usually cheaper but can shrink over time.
• Softer silicone flexes for undercuts; firmer silicone holds shape for larger moulds.
• Wear nitrile gloves and work in a well-ventilated room when mixing resins and mould rubbers.
• Measure and mix carefully, as inaccurate ratios cause soft or sticky casts.
