sulfides or oxides

Ingredients

sulfides, oxides

Preparation Steps

Original Recipe Text

Umayyad lead glazes were mixed with metal sulfides or oxides to achieve a range of pigmented colors (p. 28). These were applied to earthenware vessels to create a barrier that prevented liquids from transpiring (p. 28).

Evidence

"Both transparent and pigmented glazes were used, Umayyad lead glazes were complemented with sulfides or oxides to produce pigments such as green, mustard yellow, brown, purple and cobalt."

Remarks

Glazed vessels were appropriate for containing liquids as the glaze prevented perspiration, while unglazed earthenware was used specifically for its porous nature to keep water cool (p. 28).
