Furnace use High strength refractory Sic kiln shelf 500*370*15mm

1. Introduction
Silicon Carbide Kiln Shelves are thin, lightweight made from an advanced Nitride-bonded Silicon Carbide composition, stronger and weigh half or less compared with a conventional 1” thick Cordierite kiln shelves. They do not sag or warp after many firings under heavy loads and suitable for temperatures up to 2600°F and a great choice for Gas, Soda and firing kilns. They are about twice the cost of Cordierite or High Alumina kiln shelves cost.

Kiln shelves should be stored standing up on their edges. Storing them flat makes it more possible for them to break or cracks. Keep shelve dry. If they do get wet (e.g., after applying kiln wash), heat them slowly and soak for a few hours at 300° F.
Kiln wash is a layer of material between your pots and kiln shelves protecting your kiln shelves during glaze firing preventing glazes from sticking to your shelves. Unglazed pots can stick to the kiln shelf if the clay body vitrifies. Kiln wash is made of silica sand, alumina hydrate and kaolin. You can mix your own kiln wash or purchase.

Glaze comes in contact with the kiln shelf when something unexpected occurred (e.g., running glaze, tipped over pot) during the glaze firing even if you wiped glaze off the bottom or used stilts. If kiln wash was not used in the above possible scenarios, your pot will stick to the shelf and break trying to remove it . You will have to grind the glaze off the shelf’s surface, remaining glaze soaked into the shelves will continue to erode the kiln shelf.

We also recommend applying kiln wash to the brick on the bottom of the kiln to prevent from glaze drip damaging the soft brick.

Warning: Stay away from electric kiln elements – kiln wash will corrode and reduce the elements life expectancy.
