Transferware -
Transferware is a method of decoration that dates back to the early 1800's. It is a method whereby the pattern is "transferred" to the object by a piece of paper that carried the design from an engraved copper blank onto the pottery, before the final firing and is an "under glaze" decoration. Most transferware is mono-chromatic, or one color. However, you will find polychromatic - ( multi  colored ) examples, such as the one pictured below.


Although blue was the first color used in transferware, and the most popular, there are several colors
including Mulberry, Brown, and Green.

Hand Painted - Note the brush strokes!
Items may be handpainted before or after glazing. Painting done over glaze is generally referred to as "Cold Painted".

Quite often the glaze on a piece of pottery is the decoration! Many glazes take years of research to develop and are passed down from generation to generation. Some glazes and techniques have been lost and have proven impossible to duplicate.
Below are some common examples of pottery where the glaze was a primary feature of decoration.
