Alginate Chromatic 450g Bulk Box of 24

Our colour-changing alginate in bulk: a box of 24 individual 450g bags, ideal for schools, workshops or busy studios running multiple life-casting sessions. Each bag shifts colour through mixing, pouring and setting so timing is never a guessing game.

Adjust the powder-to-water ratio for a firmer or springier mould, and every bag comes with its own instructions.
