Conventional, ram pressed silicon carbide shelves are the traditional “work horse” shelves used by potters firing to cones 9-12 in natural gas, propane, wood and multi-fuel kilns. Our traditional silicon carbide shelves are oxide bonded and over the last 40 years have proven to be a sound investment providing years of service life in demanding firing applications including gas reduction, wood, soda and salt.

ADVANCER kiln shelves are 19 times stronger, and weigh 50% less than conventional 1” thick cordierite kiln shelves and are made flat to stay flat so there’s no warping even after many firings under heavy loads. Advanced nitride-bonded silicon carbide (NSiC) is distinguished from conventional nitride-bonded silicon carbide in that it is significantly stronger, thinner and much more resistant to oxidation; suitable for temperatures up to 2600°F!

The cost effective alternative to our Advancer® shelves for a variety of firing applications including Reduction, Soda and Wood firings. Cryston® TW is not recommended or suitable for use in electric kilns due to high electrical conductivity rate. Cryston® TW shelves are slip cast nitride bonded SiC made from fine grained mix used to manufacture beams, posts, plates and unique shapes with sections from 6.4- 10mm. They are part of our exclusive LO-MASS® product line that offers thinner, light and stronger products.

Wet, air setting high temperature general purpose, economical refractory mortar. Should be thinned with water. Max service temperature 3000 F.
$50.26 / 55 lb pail
Similar to Sairset but with increased workability and better bond strength. Can be used as is or thinned with water. Can be used for skim coating. Max service temperature 3200 F.
$62.30 / 55 lb pail
Dry form of Sairset for greater economy.
$50.60 / 55 lb bag
Dry, chemical setting mortar ideal for weatherproof applications such as outdoor ovens and chimneys. Max temp 2700 F.
$98.75 / 50 lb bag
2500° Maximum Service Temperature. Strong, dense, general purpose castable ideal for many applications including furnace linings, special shapes, kiln skews, keys and oven floors. Medium aggregate size. 122 lb/ft3 density.
$41.25 / 55 lb bag
3000° Maximum Service Temperature. High alumina castable. Abrasion resistant with good resistance to numerous slags. Shows expansion rather than shrinkage after heating to elevated temperatures. Good resistance to spalling. 140 lb/ft3 density.
$48.95 / 55 lb bag
2200° Temperature Limit. Lightweight castable with low thermal conductivity and good strength. Good all-around backup material. Used for lightweight panel construction, flue and duct linings and complete monolithic linings where there is little or no abrasion.
$51.70 / 55 lb bag
2600° Temperature Limit. Meets the demands of severe furnace and boiler environments. Suitable for hot face linings, furnace stacks and flues. High strengths reduce cracking from mechanical abuse or steel shell flexing. Low iron content minimizes destructive CO disintegration attack by reducing furnace atmospheres. Lower water content for placement reduces internal steam pressure during initial heat up.
$50.82 / 55 lb bag
Durablanket® refractory ceramic fiber products are high strength, needled insulating blankets that are made from spun ceramic fibers. The extra-long spun fibers, cross locked through a unique forming process, produce a blanket with exceptional handling strength. Blanket products are completely inorganic and available in a variety of temperature grades, densities, and sizes.
1" x 24" wide 8lb | $3.50 / sq ft
Insulfrax® S Blanket from Unifrax is their “green” blanket which was developed from a calcium, magnesium, silicate chemistry to provide thermal insulation at continuous operating temperatures up to 2012°F (1100°C).
