Chromatic Alginate 500g – Fast‑Setting Precision Mould Making Material

Chromatic Alginate 500g is a natural, seaweed‑based mould making compound designed for producing high‑detail, flexible moulds quickly and safely. When mixed with water, the fine powder changes colour from white to purple, clearly indicating when it is ready for moulding and when it has fully set.

Setting within minutes, this non‑toxic material creates durable moulds suitable for casting plaster, plastics and low‑temperature metals. It offers a cost‑effective alternative to silicone while maintaining excellent detail reproduction.
