Saggers, a tool used in firing clay products, are usually made from "fireclay" and are resistant to the high temperatures produced in kilns and ovens.
   The saggers used at the Pamplin factory were about 8-inches high and 16-to-18 inches in diameter.
   Pipes would be placed in the saggers before they were set into the kiln. The saggers protected the pipes from open flame, smoke, gases, and kiln debris.     The saggers here were recovered by archaeologists during excavation at the factory.
