Advanced Refractory kiln furniture pottery use Silicon carbide PLATE
1. Description
silicon carbide ceramics have the excellent properties of high bending strength following rising temperature, thermal shock resistance, oxidization resistance, corrosion resistance.
SiC ceramics can be made such as beams, batts, rollers, thermocouple protection tubes,burner nozzles, other special shaped structural parts and so on.
SiC is widely used in shuttle kilns, tunnel kilns, roller kilns and other fuel industry kilns.
Kiln wash is a layer of material between your pots and kiln PLATE 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.
