Prepare Supplies - Measure Out Water How Much? Add the alginate to the water and begin mixing. Mixture starts out lavender and quickly turns pink, but will loose color as it is mixed Once mixture has lost its color, it is about half way through the setting time and is ready for molding. Hold the foot in the mixture.  Toes can wiggle, but don't remove the foot from the mixture until the mold is set. If using the foot container to cast a hand, insert at the angle shown. You know the mold is sent with it it turns rubbery, is no long fluid or sticky, and starts to separate from the foot. Ease the foot out by moving side to side revealing the mold. The molding material cleanly separates from non absorbent surfaces, but will stick to clothing and other porous items. Prepare casting stone as directed. With the toes pointing down in the container, begin adding casting stone.  Turn the container to coat all inner surfaces of the mold. Pop surface air bubbles In the toes down position, fill with casting stone as much as you can. As you tilt the container back to its original position, continue to fill with casting stone. If using in a shadow box, you may only want to fill to the top of the foot and not up into the ankle. After allowing to set for 1-3 hours (depending on size), the casting can be demolded. The top of the ankle area may be sanded to smooth over rough edges. After drying in a well ventilated area for about 1 week, the foot casting will be ready for a sealant or finish paint (if desired).<p>
