What are the markings found on a purple clay teapot?
Actually it's 車寶鍾製. Accidentally found one item selling online with the same seal. https://tw.bid.yahoo.com/item/%E6%97%A9%E6%9C%9F%E8%80%81%E8%8C%B6%E5%A3%BA-%E8%BB%8A%E5%AF%B6%E9%8D%BE%E6%AC%BE-100433885065

車寶鍾 is the name of the person who made this.
