Re: Bronze Clay?
I have been reading the progress here for months now, quite inspiring. Always exciting when things go boom! Motivated me to read patents and articles. Burkhard, good to see Aussie initiative! the patent for the bentonite mix suggested using an organic substance for greater viscosity...sugar was mentioned. Did you try that? Experience with ceramics, joining pieces to avoid cracks...if you cross hatch and slip the join, blend the join and the seal the sculpture in a plastic bag leaving it for a few days to redistribute the moisture across the join has been successful..might work with the bentonite mix. An article looking at the oxidation, weathering and porosity of the sintered bronze written by Dr German sounds promising too and shows [microscopic] images of the process.
