Mould making for beginners: alginate, plaster of Paris, and liquid latex
Mould making is more accessible than most people realise — once you understand what alginate, plaster of Paris, and liquid latex each do, the whole subject opens up. Alginate is a seaweed-derived gel that sets in minutes and captures precise surface detail — ideal for life casting but single-use. Plaster of Paris is the classic casting material, mixed to a creamy consistency and poured into the mould to set hard. Liquid latex builds up in painted layers to create flexible, reusable rubber moulds for repeat casting. This complete beginner's guide covers all three, explains when to use each, and walks through a simple first project. All stocked at Craft and Canvas.
