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. Obviously, the original name of a German company was in German. "1895–1900" means the mark may have been used during those years.
Research and experience will tell you if the color, texture, weight, design, or general "feel" of the piece is right. When translated, several possible forms could have been used. If the initials in the mark were directly connected to the foreign name, it may have a more awkward translation. If it is a date such as "1895 ," it is not known how long after 1895 the mark was in use. The date could have been used at any time during the years on either side of 1895. Most of the time they are from the first year that any predecessor company worked until the last year any successor company worked, provided that the name or management was continuous.

One of Delftware's main features is its distinct blue and white coloration, made when manganese purple is combined with a blue underglaze.
