[Original 1931 text] "The ancient pottery of Mohenjo-daro frequently has sand or ime, or both, mixed with the clay, more often in the painted ware than in the plain ware. There seems to have been a natural admixture of sand in the alluvial clays used at Mohenjo-daro, but so fine in quantity that it cannot be detected under a glass of moderate power." [Marshall, Vol. I, p. 289]
