Ceramic Furnace use refractory Cordierite Batts 450 * 400 * 15 mm
1. Introduction
Cordierite has excellent thermal shock resistance, good strength and can be formed by pressing, extruding, casting and vibrating into complex shapes. Cordierite mullite kiln furniture is widely used in porcelain, heavy clay, glass panel, powder metallurgy, magnetic materials, green energy, food, glass, abrasives, iron and steel, mining and aerospace engineering.
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.
If firing mid to high temperature (cone 4-10), kiln shelves that are too thin will sag with time so make sure you purchase the right thickness. The shelves thickness options are ½", 5/8", ¾" and 1". The decision need to take into account the firing temperature and kiln shelve length. For example, if your kiln shelf length is 30" and you fire to cone 6, 1" shelves thickness will be a wise choice.
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.
