You do not need to vacuum the kiln for a ceramic bisque firing. But you should vacuum it before every glaze firing. Use the brush nozzle attachment.
How much will I shorten my element life by opening the kiln at 1800 degrees F for raku firing? I am firing tiles. Is it okay to have shelves spaced 3 – 4 inches apart throughout the kiln?
