Primitive Glass Paint
This head is at the style as the very earliest stained glass - it is almost exactly at the same character as the painting on the Ascension Window at LeMans and the painting on the St. Lawrence window, I think it is at the east end of the Cathedrat at Poitiers France

The glass is almost a natural flesh tone and the paint looked blackish brown on the surface when wet and about black when looking through it.
I produced practically the same paint
