To make the faux-marbled ring cone we first needed to make our own cone-shaped silicone mold.

Our work as #ResinCraftsCreativeTeam members with ETI-USA has given us an opportunity to experiment with many different products such as this EasyMold Silicone Putty. It’s ideal for a wide range of impression type mold applications including resin, epoxy, plaster, concrete, wax, soap, low melt metals, baking, chocolates, ice cubes and air dry clay.  The creative possibilities are literally endless!

We also recently made these faux-stone beads using Easy-Sculpt self hardening epoxy modeling clay. Check it out, can you tell that they’re not real stones?

Supplies Needed to Make a Cone-Shaped Silicone Mold

Instructions for a DIY Cone-Shaped Silicone Mold

Step 1: Create a cone out of card stock paper

  1. To begin, draw and cut a circle out of the card stock paper. The height of your cone will be determined by the size of your circle. For example, I started with a 6″ wide circle to make a 3″ high cone.
  2. Draw a triangle wedge about ¼ size of the circle and then cut the triangle wedge out of the circle.
  3. Wrap the cut sides of the disc together, overlapping as needed until the base measures about 1 ½” diameter. Then tape the paper cone closed.

Step 2: Make the silicone mold

Remember to work very quickly!  Not exaggerating here:  EasyMold Silicone Putty has 3 minutes of working time at regular room temperature!  Mix only enough to make one mold at a time.

1. Start by measuring equal sized amounts of components A & B.  For this 3” high cone, my components were each about the size of a small golf ball.

2. Next, quickly knead together equal amounts of components A & B until you get a uniform colour (about 1 minute).

3. Roll the kneaded components into a ball and then flatten so you have enough to wrap fully around the outside of the paper cone.  Press putty firmly around the paper cone.

4. Leave the paper cone inside the putty for 25 minutes while it cures.

5.  Finally, remove the paper cone. The new silicone mold needs to cure at room temperature for 24 hours before using it with the FastCast product. Be sure to read and follow the manufacturer’s instructions for cure times when using a silicone mold with other materials.

IV wanted to use some of the wood decorative pieces on my furniture for added decorative appeal. These are ornate curved and sometimes floral pieces that have a flat back for smooth adherence. But, they are so expensive to use on these refinished pieces, your doing it for purpose of a resale standpoint. Do u believe the silicone molding would work on these wood pieces that may be able to make them out of plaster of Paris or a similar liquid product. And what's the probability that the silicone mould would pull away and release itself from the molded piece? Thank you for your answer in advance.

Hi Tod. Yes, those pieces do get really expensive! While you could use the Silicone Putty which we used for this project, we'd actually recommend the EasyMold Silicone Rubber ( ) . You'll see the sample on the box is exactly what you're describing. The rubber is more of a liquid so will give you the detail you need. Then, we'd suggest looking at the FastCast product to make the pieces with if you are planning to paint them ( ). Once cured, the silicone sticks to very few things so we're quite confident that you'll be able to get your pieces out of the mold without a problem. Let us know if you have any further questions! -Jane
