A saggar is a reusable lidded container. In the 19th and early 20th centuries they were used to protect porcelain and stoneware from the vapours, ash or debris in the kilm.
Now saggars play a more creative role in the firing of ceramics; combustible materials are placed inside it that will carbonise or blush on the surface of the work.
To achieve the satin finish the clay surface is burnished before drying and then bisque fired.
This very tactile finish absorbs the atmosphere in the saggar more effectively each piece unique and to its particular firing.
