I came across an article in an OLD CM, May 87-Jeffery Werbock, with this idea. It is presented as a Korean technique. Are you familiar with it? When I read it, I thought about my question some time back about throwing orientation of pugged clay and s cracks from the spiral in the pug.
Wouldn't this 'eye of the clay' approach have the same issue? I was taught to put even small hand wedged pieces on the bat with the spiral cross wise so as to minimize s cracks.
This article talks about using spiral wedging to create the spiral and how coning up and pushing the clay to one side when coning down will increase the twist in the clay, to your benefit. The idea is that it is easier to open and throw because you are working with the spiral. The focus of the article was throwing large. The potter in the illustrations opened the tall slender lump of clay with his fist, going into the clay elbow deep. The first pull was from walls already 12" tall.
