Edmund de Waal's book The White Road narrates his journeys
to porcelain producing areas of the world. Porcelain was originally
made in Jingdezhen in China but in 1746 a porcellaneous clay was
found on Tregonning Hill near Rosudgeon in Cornwall. This clay
was used to make porcelain pots but not in recent times.
Peter Swanson lives close to Tregonning Hill and after reading
The White Road was inspired to venture up the hill, dig some clay
and try it out. As the group of guinomis above testify the clay
fired well. Peter doesn't plan to go into full production but
will on occasion make more.
