Description BabyGel™ 2 alginate is a fast curing, skin safe alginate mold material that is ideal for making accurate reproductions of your baby or child’s hand or foot. BabyGel™ 2 is unique among other alginates in that, when mixed with water at 80°F/27°C, it changes color from pink to light grey as it cures.  This visual indicator makes it easy to determine when to insert the baby or child’s hand or foot into the mold gel. Mold will cure in about 3 minutes. You can cast LiquiStone™ plaster or FUN Silicone™ into the mold to make a reproduction.
