What are the working stages of metal clay?

There are three working stages; lump clay, leather hard or green stage and fired.

In the lump clay stage, the clay can be rolled, textured, bent, slumped, domed, moulded, spread onto surfaces or free-formed. At this stage, the clay will dry out if left open to the air and needs to be kept in a sealed container or cling film when not in use.

The leather hard or green stage is achieved by leaving the clay open to the air to dry out. At this stage, the piece can be filed using salon nail files, sawed, polished, drilled or cut. It is very fragile at this stage and breaks easily so it needs careful handling.

When the clay is completely dry it can be fired. Once fired, the metal can be worked in the same was as sterling silver. It can be drilled, sawed, hammered, polished etc.

How thick should my clay be?
This depends on what you are making, how deep the texture you're using is, if you're putting texture on the back and the front and also to some extent personal taste. If you're making a pair of small plain earrings, you can roll the clay out to three cards thick. This should make a light pair of earrings that are strong enough to withstand the wear. If you're using deep texture you should go up to five or six cards thick. Deep texture on the back and front of a piece may require your initial rolling to be even thicker. If your piece is going to get lots of wear, like a pendant with a wrap over bail, the bail part should be a little thicker so it can withstand the wear. You will probably know if you've gone too thin when you try to pick the piece up....

Always stir the paste with a plastic or metal spatula, never with the brush. If you're making paste from scratch, use the spatula on a flat surface, like a ceramic tile or piece of glass or plastic. Squash the lump of clay and add distilled water slowly, working this into the clay bit by bit. Time spent bringing the paste to the right consistency slowly will pay off with smooth paste. ...
