When did the R&D for Silver Porcelain by Tiancheng products begin? And when did mass production start?

R&D for the Silver Porcelain by Tiancheng craft began in 2012 in collaboration with Professor Li Bo’s team at Tsinghua University, followed by three years of basic experiments and pilot production at Handan College. The craft completed mid-scale testing in 2019 and was put into mass production at the Green Technology Innovation and Manufacturing Industrial Park in Fuxing District, Handan City.
