Does the size of the charcoal container matter?. or is it designed
to fit in their kiln specificaly
The container needs to fit in your kiln. As you have a small kiln,
you need a smaller container. Go to a hardware or kitchen store and
purchase a small stainless steel bowl or measuring cup that will fit
in your kiln (take a measuring tape or ruler with you and your kiln
dimensions). At a hardware store, you should be able to purchase a
flat sheet of stainless steel that can be cut to a size that will
cover your bowl or measuring cup.
Activated carbon can be purchased from a metal clay supplier or at a
pet store–it is the stuff used in fish tanks. However, if purchasing
from a pet store, be aware that you should purchase coconut based
carbon that has NOT been acid washed. The coal based carbon is ok for
bronze clay, but not recommended for copper clay because the quality
is not as consistent as the coconut based carbon.
