All my work over 10 inches in height is hollow. I build using
the coil method.
I've used the same clay formula for years. It's similar to
a clay that may be purchase at Campbell's
Ceramics called "Allen Rosenbaum's Terracotta"
(Allen was the creator of the formula). To the best of my
knowledge, the main difference between Allen's and my current
formula is the grog: I use a fine grog, Allen uses a medium
weight grog.
I love building
large. I find the challenge of it inspiring and the results viscerally
satisfying, but there are logistic issues to consider. Moving a
400 pound plus sculpture from point A to point B requires some serious
upper body strength.
