Is it Flow Blue China? - By: Judith McAllister, 2010-01-14

Many manufacturers experimented with the blue flow glaze trying to perfect the cobalt blue color by adding other pigments to the mix. This made grayer, lighter, or even blacker shades of blue. Today, some collectors prefer the gray or black colors. Flow blue plates are turned over to determine if the blue is on the bottom because the glaze does not go through the china. If a broken piece of china is examined, you will observe the color does not penetrate through the piece.
