I am delighted with outcome of my four test tiles. I set out the see the different shrinkage of porcelain paper clay when firing at stoneware and earthenware temperatures. At the same time I wanted to see how I managed to get on with adding detail with a Design Liner (in black). Because the colour flow isn't so easy to control it adds an organic quality of line.
The shrinkage is quite remarkable, especially at the higher firing temperature of stoneware (on right). This will be useful when size is an issue when making items in paper clay. Accounting for shrinkage I would need to make them about 13% larger in size.
