Stoneware marbles are a dense, fired clay marble with salt glaze on them. These marbles are made in the same manner as salt-glazed stoneware crocks and jugs and may very well have been made by the same makers. The marbles have similar blue patterns on them. Usually the patterns are spongeware-type or splatterware-type, or else they tend to be bands encircling the equator.
