Clay™ is metal clay in the form of powder. The powder is already mixed
with a binder and all you have to do is add water. The advantages over
pre-mixed clay are that you won't have to worry about shelf life, and
that you can easily bring the clay to the desired consistency. Since it
contains no preservatives the clay is very forgiving, soft, pliable, and
sticks well to itself. It mixes quickly, with no mess. Hadar's metal clay powders are available in a variety of colors and formulations of bronze, copper and steel.
