Metal Clay Types, Techniques and Helpful Resources
What Is Metal Clay?
Metal clay not a clay at all, but rather a malleable form of metal. It is made by mixing microscopic particles of powdered metal with an organic binder and adding enough water to hold them together.
What Makes It Unique?
In this clay-like form, the metal can be molded, impressed with textures, extruded, rolled out, formed into thin log shapes (called snakes or coils), and joined to itself permanently with just water.
After metal clay has dried it can be sanded, filed, drilled, carved, embellished with fresh (moist) metal clay, and joined to other fresh or dried metal clay components with just a brush moistened with water and a small amount of fresh material—fresh clay, syringe clay (very moist clay prepackaged in a plastic syringe that can be extruded, used often to embellish lump clay), or slip or paste (lump clay thinned with water). It also comes in a special form called metal clay paper or metal clay sheet that is a thin, paper- or vinyl-like sheet that remains flexible even when dry. During firing at very high temperatures with a torch, in a kiln, or on a gas stovetop, the organic binder burns off, any remaining moisture evaporates and the particles of metal clay come together as a single, solid piece of metal that retains the shape and texture it had prior to firing. The piece shrinks somewhat as the binder and water are are burned away/evaporated and the metal particles move closer together to fill in the spaces left by the binder and water. The extraordinary experience of putting a piece of metal clay into the kiln and a little later taking it out again in solid metal form seems almost like magic - a modern-day form of alchemy!
Metal clay truly is an amazing material that allows even those without traditional metalsmithing or bench skills to create detailed, handcrafted, one-of-a-kind jewelry, small sculptures and other objets d'art with relatively few tools, supplies, and pieces of equipment (although once you start working with metal clay, which is highly addictive, there are many other metal clay tools, supplies and equipment you're likely to covet and perhaps acquire over time).
