Every collector knows that the quickest way to identify a piece of pottery or porcelain is to identify the mark, but sometimes it's unreliable because marks are often forged and changed. This is a listing of the better-known marks and backstamps and enough information so that you can learn more about your porcelains. Research and experience will tell you if the color, texture, weight, design, or general "feel" of the piece is right. This will help you identify the mark.
