Our Monday morning Art Group meets in the back room of the Gallery every Monday morning and we aim to try different techniques and media.... so one of our number is an accomplished potter, and he fires many of his pieces in the Raku style.
You can read about the Raku process here.
Our first task was to make a pinch pot, starting with a shapeless lump of clay, shaping it into a ball, then making a depression into the middle, and working the sides until it looked sort of like a cup. Here's mine. This was after it had been fired once and I had added white glaze inside, and blue glaze on the outside with a couple of black blobs. I had no idea what this would turn out like.
