It was only in 1984, when the Tak Om Koi Burial Sites were found along the Thai-Myanmar border, that Burmese ceramic production came to light. Prior to this, very little was known, but the idea that Martaban had produced ceramic jars was already widespread. In addition, the glazed plaques at Bagan were well-known, and earthenware pottery had been discovered in many archaeological sites.
At Tak Om Koi, however, new types of wares (mainly green-and-whites), were identified and Roxanna Brown, the late but respected expert in Southeast Asian ceramics, included a chapter on Burmese wares in an update to her Master of Arts thesis, Ceramics of South-East Asia: Their Dating and Identification (1988).
As this is a relatively recent discovery in the history of Burmese ceramic wares, the details are still sketchy.
