After speaking to Andy in ceramic today it would appear throwing a plate is a lot harder than it looks. Also Due to it being closer and closer to dead lines Andy said its not too likely that the kiln will be free. Especially for lazer tran as you need to have a slow long change in temperature.
He has got a cheaper version that you don't need a kiln for and can be printed onto inject printer.
How ever this mean i will not get to use the process i originally wanted but its an easier way to get the same outcome.
I plan to buy some plates.
