It's a bit of a pain in the butt to make the calcined clay but you make a small batch and you're set for years. Flatten balls of clay into flat patties and let them dry completely. Crush them fine with a rolling pin and sieve finely. Place the clay powder in an UNGLAZED bowl and fire it. Place your calcined clay in a container and mark it. When ready to use, mix a little calcined clay with the glaze color you are using to make a paste/putty. Fill in your hole and fire. Since the clay dust is already fired, it won't shrink anymore. PS did you see the Pele/Volcano Swap Thread? You have a volcano themed piece and are welcome to join if you can finish by 8/8. PM me if you have any questions Mike
