My work has always been made on the potters wheel until last year when I started to use another process which doesn't use the pottery wheel.
This hand building process uses a couple of methods to flatten out the clay. Either a slab roller can be used or a wooden rolling pin. The slab roller is a large piece of equipment that gradually rolls out the clay to a required thickness. I prefer to use a rolling pin as I have been fortunate to have been a potter for long enough to be able to judge the thickness of the clay just by the feel when I brush my hand over the clay surface.
