Description:A saggar maker and his apprentice at work in a tile factory in the Potteries. The apprentice would be known as a 'saggar makers bottom knocker'. The saggars were made of marl, which was hard wearing and could withstand many kiln firings.
Ware would be placed into the saggar in order to protect it from contamination by smoke, etc during firing. The bottom knocker would make the base of the saggar by knocking it into shape using a large flat mallet.
