Black Longpi pottery from Manipur is made from ground black serpentinite stone and special brown clay found only in Longpi village. The products are manually shaped, polished, sun-dried, and fired in a bonfire. The black colour of Longpi ham results from the reduced firing of the ware, while polishing the heated earthen pots with a local tree leaf right after firing gives them a beautiful shine. Gangadhar – Soul for Earth, brings you this functional and beautiful heritage pottery! Wash & Care: Wash with warm water; use mild soap and a soft sponge if required. Do not scrub. Dry thoroughly before storing.
