Rare Medieval Islamic / Persian wheel-thrown pottery bowl with a fantastic turquoise, green- and mother of pearl coloured glazing. Pieces like this example are the result of technological innovation at the end of the 10th century. The body of this vessel was made of finely ground quartz mixed with clay; this created a white surface upon which the artists could pour the colorful glaze and sometimes paint additional designs. The glaze is alkaline, with a copper base to give it its color, and would be poured over the clay. Manganese creates the black motifs inside the bowl. Scholars believe that such pieces may have been inspired by the blue and white glazed pottery that travelled the Silk Road from Tang Dynasty China; however, the end result was clearly not just an imitation, but rather an entirely different, radical style. Diameter: ± 11,5 cm Height: ± 5 cm Condition: good and solid restored condition. Collector tags from around the 1900's present on the outside of the bowl. Fantastic semi-translucent spectrum of colours from the light mother of pearl to turquoise, green and black. See images for full impression.
