Malleable

A sheet of copper doesn’t begin life as a cuff. Getting it there takes tools, a little persuasion and a useful property called malleability.

Malleable describes a material that can be hammered or pressed into a new shape without breaking. In jewelry making, that means metal can be flattened, textured and formed into something far different from where it started.

Copper, silver and gold are familiar examples. Each responds differently under the tools, and the metal’s alloy and condition affect how readily it can be worked.

There’s a catch, though: workable doesn’t mean endlessly workable. As many jewelry metals are hammered or bent they become harder and less willing to move – a process called work hardening. Keep pushing them too far and cracks can develop. Annealing, a controlled heating process, restores softness so the shaping can continue.

That hammered copper cuff in the illustration tells both stories: malleability allows the metal to take its shape, while working it changes how it behaves.

A small word for a property that opens up a whole world of possibilities.
