The print is produced by embedding a limp leaf into the glaze before it
dries. When dry, the leaf and background glaze are coated in an emulsion wax.
When dry, the leaf is removed, and the remaining print is coated in a thin
layer of a contrast wash.
The contrast wash is Kaolin + Rutile mixed with water and CMC gum.
Clay body is a grolleg porcelain from Tacoma Clay Art Center.
