YiXing is famous for its Zi Sha (Purple Clay) wares. To protect limited Purple Clay resource, YiXing government banned Purple Clay mining in 2005. Although many real Purple Clay wares on the market now are made from Purple Clay mined prior to the ban, many cheap Purple Clay products are made from faked clays.
YiXing government announced recently that it will lift the mining ban by end of this month. This no doubt is a good news to Purple Clay collectors. According to recent news, actual mining location and quantity will be decided after necessary assessment.
