The instructable is to make a 3-D hollow-form pendant for a necklace. We make the hollow form by coating a Completely Dry organic armature (Popcorn, in this example) with 8-12 layers of Precious Metal Clay (PMC) Paste.
When fired, the popcorn will burn away, leaving only the pure (99.9%) silver from the PMC in the shape of your popcorn kernel!
Jar of PMC3 (Precious Metal Clay) paste.
1 inch piece of Fine Silver wire (dead-soft).
Victory Wax (or cheese wax).
Shallow pan for water.
Metal measuring cup for melting wax.
A craft or ceramic kiln of some kind.
Small, smooth jawed pliers.
Wire cutter or scissors.
Brass brush for polishing.
A necklace, piece of ribbon, or leather cord.
...all will become clear...
Step 1: What is this Magic "PMC" Stuff?
This product became known as Precious Metal Clay (PMC).
After drying, the PMC is heated to the fusing temperature of the constituent metal. During this heating, the binder burns away, and the metal particles sinter together into solid metal.
We will be using a form of this product which is pre-prepared to a paste-like consistency.
Basic PMC Working Tips:
Its all about the moisture, PMC can dry out very quickly.
1) Plan ahead (have your tools at hand) before you open your jar of paste.
2 ) Water can be used used to moisten the clay and smooth the surface of your pendant.
3) Dried out PMC can be reconstituted with water and reused.
