Plastic is made by mixing together a liquid plastic formula. The formula is then poured into a mold, where it is hardened into a specific shape. Liquid plastic is made by mixing resin with liquid hardener. The liquid harden acts as a catalyst to initiate the hardening process when the liquid is poured into a mold.
Find a well-ventilated area to work in. The fumes of the material used can be very strong.
Pour 32 oz. of casting resin into a paper container.
Add 1 oz. of liquid hardener. If you want to make a smaller batch, remember that 10 drops of liquid hardener are needed for each ounce of casting resin.
Stir the two ingredients together with a wooden paint mixing stick.
Continue to stir until all of the streaks within the mixture have disappeared.
