Easy Mold Making Kit; Molding and Casting for Beginners Ages 10 and Up

Kit Includes: 6 oz./171g. ComposiMold, 4 oz./114g. ComposiStone Hard Plaster, 2 oz./57g. Modeling Clay (colors vary), and Instructions.

Below are the instructions included in the Easy Mold Making Kit. Remember, you can easily learn molding and casting with this kit designed for beginners ages 10 and up!
1. Soften and shape the clay into an original sculpture. Make sure it is has a flat back and is less than 1/4” thick. (It’s best to start with simple shapes.)
2. Press the back of your original sculpture onto the bottom of the empty container that all the kit items were in. Be sure there is at least 1/2” of empty space all around your sculpture. (You can use any heat safe container as a mold box.)
3. Melt the ComposiMold in the microwave in intervals of 10 to 20 seconds each, checking the ComposiMold in between. Be sure not to boil the material!

4. Pour the melted (and slightly cooled) ComposiMold over your original sculpture so it covers it by at least 1/4”. Use a toothpick to guide any bubbles off of the surface of the clay sculpture. (You don’t have to remove the bubbles completely, just be sure they aren’t touching the surface.)

5. Let your mold solidify back to its rubbery consistency by letting it cool at room temperature or in the refrigerator to solidify faster. It should take about 10 minutes to cool in the refrigerator.

6. Remove the original sculpture from the mold by pulling it out or bending the mold away from the sculpture.

7. Mix the ComposiStone Hard Plaster at the ratio of 2 1/2 parts powder to 1 part water. This will be a thick mixture which is better for the ComposiMold and makes a stronger casting. Stir it well and scoop it into your mold. Be sure to fill the lowest and most detailed parts on your mold first. Tap the mold on the counter to be sure any air bubbles rise out of the plaster mix. Hold your mold up and look at it from below. Because the mold is see-through, you will be able to make sure the plaster mix made it’s way into all the areas of the mold. This process all needs to happen very quickly because the ComposiStone hardens in less than a minute.

8. Let this small casting harden in the mold for about 10-20 minutes. Turn the mold over and bend it away from your casting. The casting should easily fall out of the mold onto the table. Let it completely harden for 24 hours.

9. Repeat step 7 to make as many castings as you want in this mold. If the mold begins to loose detail after multiple castings, you can remake the mold of the same sculpture (if it didn’t fall apart) OR sculpt a different shape and make a completely different mold! You can clean your mold with a cold damp cloth. If it begins to dry out during the casting process, spray the inside of the mold with vegetable oil and keep covered when not in use.


10. Get creative! Paint your ComposiStone castings and turn them into functional art pieces by gluing a magnet to the back, drilling a small hole in the top to string a leather chord into, or using them as game pieces.
