Here are some new jars I ran across today at an antique shop. They are not particularly old, probably early 20th century. They are great for processing  and recycling clay, and for storing glazes. Plastic buckets quickly degrade in the sun or leave little shreds of plastic if you use a drill mixer, but these stoneware jars are thick enough to stand up to the drill mixer, and they can sit in the sun without degradation. I got all three of them for about $100.

The clay used is very rough, as in poorly wedged, and you can still see swirls of different color clays in chipped areas. The big one has the wadding marks on the rim from having another jar stacked on it for firing. The one smaller jar has a couple of stones erupting from the surface, about as big as my thumbnail. The big one also has a couple of holes from material that burned out in the firing, leaving a void.

The big jar is about 36″ tall, the smaller ones about 22″.
