Imitation, as good as real

I've been looking at very crafty imitations of Swansea items this week. Swansea and Nantgarw were two factories in Wales in the very early 19th Century, and they made some of the most beautiful porcelain ever made. The local Welsh clay was unique, but it was also very costly to work with: the best quality had a kiln waste of 90%, meaning that only 1 in 10 items would come out of the kiln in a usable state!
