| Summary: | An organic substance has been identified in the top layer
of Northern Black Polished Ware (NBPW) excavated from the Wari-Boteshwar and
Mahasthangarh sites in Bangladesh. NBPW is the most distinctive ceramic of Early
Historic period and the technique of its surface gloss acquired numerous theories. This
particular paper is an analytical study of collected NBPW sherds from these two sites
including surface observations using binocular and scanning electron microscopes and
Thin Section Analysis of potsherds. Thin section analysis identified two different
layers of coating on the surface of the NBPW. One layer is a ‘slip’ (ground coat) and
the other is a ‘top layer or top coat ’. The slip was made from refined clay and the top
layer was derived from organic substance. Microscopic analysis confirmed the solid and
non-clayey characteristics of the top coat. |
