Velvety foetus didn't turn out bronze at all..
Experimented with mixing own glazes and slips using the manganese dioxide, copper dioxide and red clay, but it didn't quite turn out as expected! The spherical object is a tester displaying the desired finish, but it ended up having this velvety-black finish, which I think works better on this form as it looks softer and more tactile. I did bisque fire it, then paint the glaze/slip on, then fired it again, but you can paint the oxide slip onto unfired clay and put it straight into the kiln and fire just once.
The last image is the slip cast 'foetus' next to the wax one, which shows the shrinkage when it has been fired. It doesn't compromise the form or concept at all, but it's worth bearing in mind when making future work.
