Made for both imperial and local consumption, as well as for export to Japan, black tea bowls were particularly appreciated in Buddhist monasteries, where tea was drunk for its beneficial effect on body and mind as well as ritually offered to the Buddha. The seemingly humble quality of bowls of this type made them particularly appropriate in this context. The groove below the rim made them comfortable to hold, their heavy potting had an insulating effect, keeping the tea inside hot while protecting the fingers outside from the heat, and their dark interiors made for a striking contrast with the white froth of whipped tea.Jian artisans experimented within this ceramic type with dazzling results. By manipulating body and glaze compositions, kiln temperatures, the cooling process, and allowing for the intervention of chance in the firing process, Jian ceramicists created wares that display the full potential of the iron oxide glaze. One of the best known effects is 'hare's fur', in which opalescent streaks run down the sides of the bowl.A wide range of different 'Jian' bowls are in the Tokyo National Museum, Tokyo, included in Illustrated Catalogue of Tokyo National Museum.
