With a new bag of clay and a second haul of knitted hats from charity shops I made a second attempt at smoke firing.
I fired these in two batches.
The first batch didn’t work so well the fire roared to start with but in the morning it hadn’t reached the fuel in the base of the incinerator. The bowl in the bottom hadn’t fired correctly and was very brittle.
The second was more successful but I think that the clay was quite thin and meant that the a couple of the bowls broke into pieces.
Possibly not as successful as the first firing!
