Ceramic Sagger Firing

Linda and Charlie Riggs have spread the word on this process. First, the pieces are burnished with Terra Sigillatta and bisque fired to ^09 or 1650 F. Pieces are fired in a saggar, or a sealed container holding salts, copper carbonate, steel wool, bronze wool, seaweed, and other combustibles along with the pot. They are fired in a Raku kiln to 1650 degrees F. The temperature is held for 10-20 minutes to assure everything in the saggar has burned. The pieces are removed when cool to touch. Here is a simple method for making Terra Sigillatta.

Saggars are made to accommodate the pots and a 1" clearance from the surface.  Pieces are burnished with terra sigillatta. Sawdust, copper carbonate with salt, and other combustibles are added to the saggar.

Copper wire and wire wool are arranged on the pot and put into the saggar. The saggars are loaded into the raku kiln and fired. When they are cooled, they are unloaded.


Soluble Salts and article from NEUE Keramik

In May of 2018, I decided to use soluble salts I had been using in foil saggars firing them from 1250 to 1375 F. for application in ceramic saggars fired to 1650-1700. The results were stunning. I am still just beginning this process, but I will share some of the results. I am working on a publication for Pottery making Illustrated about the results of my testing colors.interview
