These bi-body strips are made by rolling two clays together in a thin sandwich. Three porcelains are being compared to a very plastic insight-live.com/glossary/48">grogged sculpture body. After drying (top) they curl a little, two toward the sculpture body and one, the most plastic of the porcelains, toward the white. But on firing to cone 8 they curl dramatically toward the porcelain side (because it shrinks alot more). Now imagine one of these porcelains is being used as a engobe on this body.
