This plate is in the TIME Icicle series and is very large: 80x26 cm. It is about 1 cm thick. The clay is rolled out, sprayed and allowed to freeze under very specific temperature and humidity conditions. There can be absolutely no wind. But it is tricky: only the surface water can freeze and not the clay itself.
These conditions do not happen often! Then the plate must be dried (leather hard) transferred to the kiln and bisqued. Hopefully it withstands the tension and forces as the kiln heats unevenly.
Plates of this size, using this technique, rarely survive all of the steps involved. It’s fun when one does!
