This is something that has to be developed over time.
It is not that any piece over a certain weight is American pottery–it is the relationship between the size and the weight that helps determine the country of origin.
Have you ever wondered why some people turn every piece of pottery over and look at the bottom?
Maybe you thought they were emptying the contents or dusting the shop!
In most of the American pottery pieces, the bottom tells more than the glaze.Here's a good example of the American Bisque wedge foot (right).Companies using a dry foot include most of the Ohio companies and some used stilts for some of their ware lines.The bottom shows the name, if there is one, the color of the clay, the way the piece is fired, and other characteristics that help with the identification.If you're looking to identify a piece of marked pottery, you may want to check our American Pottery Marks and Resource Directory and compare the mark there. Since not all pottery is marked, the identification must be done with a little more resourcefulness. Most American pottery pieces have some weight to them–unlike the Japan imports of the 1940s, 1950s and 1960s that seem fairly light in comparison.
