▪ I. saggar, sagger, n.|ˈsægə(r)|
Forms: [7 shrager], 7 segur, 8–9 saggar, seggar, 9 sagger (saggard), segger, sagre.
[Prob. a contraction of safeguard n.
This explanation is supported by the existence of the form seggard for safeguard as the name of an article of dress. The earliest recorded form, shrager (quot. 1686 below), seems to be a corruption due to etymological association with G. schragen to prop up; perhaps it may have been invented by the German workmen employed in the Staffordshire potteries.]
1. a. A protecting case of baked fire-proof clay in which the finer ceramic wares are enclosed while baking in the kiln. Also, more widely, any case made of refractory material or cast or wrought iron used to protect objects while in a furnace, as during annealing of iron castings.
