Instructions
Seek stoneware that appears shiny on the outside of the crock. The shininess occurs from a process known as vitrification. The surface of antique crockery will appear glassy because it contains substances that have glass-like properties. Look for stoneware decorated with light blue, purple or tan designs to help distinguish antiques from modern reproductions.
Glaze over the outside of the stoneware with your hands. According to stoneware crockery experts Bob and Carol Raycraft, the original process of glazing crockery included tossing salt on the drying stoneware. This step resulted in a sandy surface that is often difficult to reproduce.
Examine the shape of the stoneware, whether it is short or tall. Look for tall pots that have wide middles and a distinguishable lip. Look for short pots that are even in the middle and have no distinguishable lip.
Look for indications of artistry although the art is usually not overly ornamental. According to the Raycrafts, although the more elaborately decorated and hand done pieces tend to get higher bids, pieces that stick to traditional folkart also have great value. Much antique stoneware crockery also contains the names of geographic locations, such as stoneware produced by regional producer like the Myers of Texas. These pieces are more valuable than unmarked crockery.
