The Importance of Vacuuming the Kiln |
The Importance of Vacuuming the Kiln One of the easiest kiln maintenance tasks you can perform is regular vacuuming. This is especially important if you fire glazes. Vacuum the kiln before every glaze firing. Use the soft brush nozzle on a vacuum cleaner. Be sure to vacuum the element grooves, the inner surface of the kiln lid or roof, and the underside of kiln shelves. Vacuuming the grooves is essential if you have had anything explode inside the kiln. Pieces of greenware that lodge inside the grooves can burn out an element. Vacuum the kiln often if you use silica sand on the shelves. The sand, which is used to support ware during firing, can ruin the elements if it filters down into an element groove. As you vacuum the kiln, examine the walls for glass or glaze particles that have embedded into the firebricks. Dig these out carefully with a screwdriver. Otherwise the particles will embed deeper into the firebrick during the next firing.
