ADVANCER Kiln Shelves®

Light as a feather, Stronger than any other shelf

Imitated but never equaled, ADVANCER® kiln shelves are thin, lightweight kiln shelves made from an advanced nitride-bonded silicon carbide composition. 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!

ADVANCER kiln shelves possess excellent thermal properties. Low mass and high thermal conductivity result in shorter firing cycles helping potters to save energy, improve productivity and reduce overall firing costs. Also, at only 5/16” thick, for every 5 layers of shelves you save 3-3/8” of stacking height compared to conventional 1" shelves. That can add another shelf layer for every firing!

ADVANCER kiln shelves exhibit outstanding performance in a variety of applications and firing atmospheres. ADVANCER kiln shelves are used in the studio production of commercial and manufactured clay bodies including low fired white ware, tile, stoneware and porcelain.

Versatile in Many Applications

Gas-Fired Kilns: ADVANCER® kiln shelves are most widely used in gas fired oxidation and reduction kilns. The use of ADVANCER kiln shelves has been proven to increase productivity and save money in hobby, production studio and industrial applications.

Soda Firing: ADVANCER® kiln shelves are a smart choice for soda firing where soda is introduced indirectly (not by direct spraying onto shelves). The extremely low porosity of the shelves allows for soda drips to be easily removed by scraping without the time consuming grinding typically associated with conventional cordierite or silicon carbide shelves.

Wood Firing: ADVANCER® kiln shelves have been used successfully in second and third chambers of wood-fired kilns. A combination of ADVANCER kiln shelves and conventional silicon carbide shelves is often a sound kiln furniture system in areas where direct flame impingement and temperature uniformity is a problem.

WARNING - Storing and Drying Requirements for ADVANCER® Refractory Components

ADVANCER® (silicon nitride-bonded silicon carbide) refractory components should be stored in a dry, enclosed area.

ADVANCER® refractory components exposed to prolonged moisture penetration may result in catastrophic failure (i.e., steam explosion) during any rapid heat-up process of the kiln. Accordingly, do not expose ADVANCER® refractory components to any prolonged moisture source including rain, snow, condensation, etc.

The application of kiln washes and coatings on ADVANCER® refractory components is an acceptable practice and is not considered a source of prolonged moisture.

If any ADVANCER® refractory components are exposed to prolonged moisture, the product must be completely dried before it is used at temperatures exceeding 212ºF (100ºC). As a general guideline for the drying of ADVANCER® refractory components, the product must be held slightly above the boiling point of water for a sufficient length of time to expel any moisture and as much steam as possible. The following is a recommended drying cycle for ADVANCER® refractory components exposed to prolonged moisture.

1. Heat from ambient to 210ºF (99ºC) at a rate of 50ºF (28ºC)/hour.
2. Slow heating rate to 25ºF (14oC)/hour to 230ºF (110ºC).
3. Hold at 230ºF (110ºC) for 12 hours ensuring that the entire load has reached the soak temperature before the timing of the soak has begun.
4. Raise temperature to 350-500ºF (177-260ºC) at a rate of 100ºF (56oC)/hour.
5. Hold soak temperature for 16 hours ensuring that the entire load has reached the soak temperature before the timing of the soak has begun.
6. Cool naturally/slowly by turning off the heating source.
