Although there does not seem to be any general opinion about the technology of the NBP, K.T.M. Hegde’s observations are significant. He observes: “It appears that the potters were experimenting. They first used red ochre as the painting medium to decorate the Painted Grey Ware. In the second stage they ground it with clay and *Sājji māṭṭi* to produce the black slip on the Black Slipped Ware. In the third stage, they ground it with clay and *sājji māṭṭi* to produce the lustrous slip-glaze on the Northern Black Polished Ware. All the there wares were baked in a reducing atmosphere. The NBP was their highest achievement (Bharadwaj, 1975, p.190).
