Ten-sided Bowl with High Foot

39 Ten-sided bowl with high foot Iran, Ilkhanid period, 14th century[1] Fritware painted with blue (cobalt), turquoise (copper), and black (chromium) under clear alkali glaze 9.7 × 13.6 cm (3 13/16 × 5 3/8 in.) 2002.50.85 On the interior, this bowl is divided into ten radial sections, corresponding with its sides, that feature two alternating designs. One is pseudo-calligraphic, proceeding from the center of the bowl to the rim, with horizontal elements contracting and verticals expanding. The other design is tripartite and abstract. The intricacy and dark coloration of the interior contrast with the cheerful simplicity of the outside, where the white ceramic body remains more visible through a surface embellishment of lines and dots.[2] The shape and decoration of this bowl are common among wares attributed to the Ilkhanid period, although their production place has not been definitively established. Ayşin Yoltar-Yıldırım [1] The bowl was last fired between 400 and 700 years ago, according to the results of thermoluminescence analysis carried out by Oxford Authentication Ltd. in 2012. [2] A bowl with very similar exterior decoration is in the Sackler Gallery, Washington, DC. See Cort et al. 2000, 66.
