How to Make a Silicone Mold for Polymer and Precious Metal Clays

How to Make a Silicone Mold for Polymer and Precious Metal Clays

Mold making is easy to do when you use a pre-packaged two
part silicone mold putty. Silicone putty is non-toxic and
can be used for creating simple but detailed molds. Easy,
fast, flexible, and accurate, silicone putty is ideal for
using with precious metal clay or polymer clay.

!! Steps !!

Divide the two parts of silicone putty into two pieces or parts.
You'll find that the purchased silicone putty comes in Part A and
Part B, and one part will be white, the other a different color.

* Return any unused portions of Parts A and B to their storage
containers for later use, to prevent the silicone from drying out.

* Take one piece of Part A's putty [1] and roll it into a ball. Then
do the same to a piece of Part B. It is very important that you
ensure that both pieces from Parts A and B are the same amount in
size, otherwise the finished mold [2] will not set.

* Mixing the silicone [3] putty Mix both Parts A and B
together. Mix until the piece is one color only. Don't worry –
it doesn't take long for the putty to be completely mixed.

* Obtaining an image Press the putty onto the item you
want an impression from. Remember to press firmly to ensure that
no air is trapped, then lift the putty gently from the item being
copied.

* Completed silicone mold Put the putty mold aside to set.
The setting time required will depend on the type of molding putty
used; read the instructions accompanying the product you've
purchased for a clearer idea.
Use the silicone mold. Once set, the mold is ready for use with
precious metal clay or polymer clay [4]. Simply follow the
instructions for the use of the clay and create your items.

* To use: Once the mold is set, just lay the clay on the mold and
run a roller [5] across it to transfer an impression of the mold.

!! Tips !!

* Remember to always read the manufacturer's instructions.

* Silicone putty can also be used to make more complex molds of
different shaped objects. Experiment to see what you can create.

* The mold should last a long time if cared for; keep stored in a
safe, dry spot.

!! Things You'll Need !!

* Silicone putty kit from a hobby, craft, or art store

* Plastic dividing knife or putty knife

* Clean surface for working on

* Drying surface such as wax paper or a baking rack

* Storage container
