High Strength Silicon Carbide Furnace Shelves

 High Strength Silicon Carbide Furnace Shelves

1. Introduction
High Strength Silicon Carbide Furnace ShelvesThin and lightweight, made from an advanced nitride-bonded silicon carbide composition that provides greater strength and half or less weight than traditional 1-inch thick cordierite kiln frames. They won't sag or warp after multiple firings under heavy loads, are suitable for temperatures up to 2600°F, and are an excellent choice for gas, soda, and fired kilns. They cost about twice as much as cordierite or high alumina kiln frames.

The kiln rack should be stored upright on its edge. Laying them flat will make them more likely to crack or crack. Keep shelf dry. If they do get wet (for example, after a kiln wash), heat them slowly and soak them at 300°F for a few hours.
Kiln wash is a layer of material between the pot and the kiln frame, which protects the kiln frame during glaze firing and prevents the glaze from sticking to the frame. Unglazed pottery may stick to the kiln frame if the clay body vitrifies. Kiln wash materials are made from silica sand, hydrated alumina and kaolin. You can mix your own kiln wash or buy it.

During the glaze firing process, if accidents occur (such as glaze flow, pot overturning, etc.), even if the glaze at the bottom is wiped off or stilts are used, the glaze will still come into contact with the kiln frame. If kiln washing is not used in the above possible cases, your pan will stick to the rack and crack when you try to remove it. You have to grind the glaze off the surface of the shelf, the remaining glaze soaking into the shelf will continue to attack the kiln frame.

We also recommend kiln washing the bricks at the bottom of the kiln to prevent glaze drips from damaging soft bricks.

warn:Keep away from electric kiln components - kiln washing will corrode and shorten the life expectancy of components.
