James, one of my friends has been using the Pardo jewellery clay,
which is a polymer clay that comes in a big variety of colors. She
has used the metallic colored ones, and likes them very much.
However, she said that
she fires it in a toaster over, which she sets outside as there is a
lot of odor from the melting beeswax.
I asked her if she tried torch firing it, and she said she had not,
because it would be very messy, and she was afraid of igniting the
wax. Also, she was concerned about whether or not the fumes were
toxic—another reason for firing it outside.
