Recipe Details
Ingredients
lead-tin oxide, tin-oxide
Preparation Steps
Potters coated the surface of red or buff earthenware with tin-oxide to create a white opaque surface or lead-tin oxide for a yellow opaque surface. This provided a smooth, uniform surface for further painting, acting like a 'painters canvas' (p. 37, 38).

Evidence
"Abbasid potters opted to coat the surface of a buff or red toned earthenware ceramic vessel using lead-tin oxide to create a yellow opaque glaze, or using tin-oxide to create a white opaque glaze."
Remarks
This technological development was an imitation of Chinese T'ang Dynasty porcelain imported into Baghdad via sea trade routes (p. 37).
