The Green Label era of Factory 1 (1977-1982) was a time period in which pots were still being made with high quality clay. After this period, clay tampering became increasingly common - additives such as barium carbonate, manganese oxide and iron oxide were used to achieve desired textures and coloration with low regard for purity. With the decline of the state run Factory 1 and rise of private enterprise in the 90’s, further problems of forgeries, low-quality processing, production and tampered clay have persisted into the present day.
