To make the mold
we use a material called alginate. Alginate is derived from seaweed and is
very safe on the skin. This is the same material dentists use to take
molds of your teeth.
First the alginate is mixed from a powder
until it resembles thick pancake mix, or thick yogurt.
Next the hand or foot is dipped into
the alginate and held there until the material sets into a gel
(approximately 30 seconds to 1 minute).
Once the hand or foot is removed from the
alginate, it can be rinsed in water to remove any alginate remnants from
the skin.
