These pots were produced by Yixing Factory 1 during the 1987-1992 'White Label' period. We were collecting since 10 years ago from a collector.
The zini clay used by Factory 1 during this period was very good and these pots are nicely high fired which are well suited for brewing young and aged oolong, and aged Puerh and Liubao. The wall is medium thick, the lid is slightly loose.
