Early India and Pakistan to Ashoka c10.27

c10.27

⁷ *A.I.* no. 1 (1946), 55-8; nos. 10-11 (1955), 50-2, and 143-6. N.B.P. ware has been mistaken for Greek black gloss, but, as Miss M. Bimson of the British Museum laboratory points out, there are several differences. Thus, a razor blade will run smoothly across the Greek black, whereas it will cut into the Indian black. If very small fragments are held near a magnet, Greek black is attracted to the magnet, whereas Indian black is relatively non-magnetic. Greek black, when refired, is consistently stable at temperatures of c. 1000° C., whereas Indian black shows considerable variation in its resistance to such temperatures.
