1kg CHROMATIC ALGINATE (colour changing white-pink-white, fast setting) This BabyRice Alginate is a high grade colour change (chromatic) alginate impression powder - which is totally safe for use on even the newest newborn skin as the alginate's main ingredient is seaweed! It conforms to British safety standards BS 4269 Pt.2:1991 & ISO 1563:1990). Each 1kg pack will create up to 10 hand/foot impression moulds for a newborn baby and 4-6 hand/foot moulds for a toddler aged 3. The impression mould will deteriorate quickly, so please don't make any moulds if you haven't got any plaster to hand. Each pack comes with basic instructions for water - powder ratio mix. NOTE: once the impression mould has been made, you need to make your cast within 15-20 mins (using Plaster), as the alginate will start to break down! If immediate casting is not possible, the alginate mould should be sealed in a polythene bag along with a damp cloth.
