The terracotta design is one I did last Thursday which luckily the Badger fired for me during the week. It dried too quickly however and the crack you can see appeared before firing as the clay shrank. This has been partially repaired with paper clay, a mixture of clay and pulped paper (3:1) which can be refired and should bind the gap.
Today I made these grey/white clay reliefs. One is a tile. The lumps in the bottom of the pictures are blobs of paper clay which you can see have a different texture. In an effort to mitigate the risk of cracks from shrinkage, these deluxe items have been placed on thick paper which should allow the clay to move as it shrinks. The terracotta design was left on the wooden board which is more likely to stick to the clay and make it crack especially when it is as thin as this.
