Treatment: Glazed with powdered galena on interiors of containers, never
externally. Glaze very carelessly applied, with much evidence of dripping,
running, and unintentional spilling.
Texture: Very coarse and irregular, with gravel temper protruding.
Color: Unglazed surfaces range from bright terra cotta to reddish buff.
Glazed surfaces on well-fired pieces are transparent yellow-green with
frequent orange splotches. Overtired pieces become dark olive-amber,
sometimes approaching black. Rare specimens have slipped interiors
subsequently glazed, with similar butter-yellow color effect as in
sgraffito and plain slip-coated types.
