saggar or sagger (SA-guhr) - n., a clay box or cylinder in which fragile ceramic wares are placed for protection during firing.
Which was important when kilns were heated by fire, usually by burning coal or coke, and delicate ceramics would be damaged by direct flame and clinkers/ash. Solution is to make a container of low-grade clay, and put the ceramic to be fired inside so it would be heated indirectly. Making saggars was a skilled job. They went out of use once kilns began to be fired by gas or electricity. The origin of the name is unknown, but every single dictionary says it's "possibly" or "probably" an alteration of safeguard.
