These Disc Plate Setters are the same material as our Dry-Pressed High Alumina kiln shelves. They are rated to Cone 10 for Oxidation and Reduction firing in either gas or electric kilns. They are not recommended for Salt, Wood or Raku Firings. These small shelves are sized to use as setters for firing plates. Each setter comes with (1) disc and (3) 2” x 1 ½” x ½” posts which can be positioned to create either a 2” or 1 ½” space between the shelves. Each setter can hold a plate approx. 1 ½” smaller than its own diameter. Because of their small size, rotating is not necessary. Kiln washing is advisable: see ‘Tips’ for more information.

Please note: there is no warranty on refractories! There are many factors that can cause shelves to fail over which we have no control. It is the nature of the material. Other than shipping damages, no claims can be made on refractories.

Kiln wash is used to protect shelves from glaze drips and contact sticking (when the unglazed “foot” of a pot fuses to the shelf during firing due to the degree of melt reached in the clay body itself). Commercial kiln washes often bond to the shelf surface and are difficult to remove making shelf rotation impractical. We recommend (2) possible alternatives:

1) Mix EPK and ALUMINA HYDRATE. Run a series of tests with a line blend as follows: 10% EPK to 90% ALUM., 20% to 80%, 30% to 70% etc.

The 10% EPK : 90% ALUM. mix, when applied as a thin wash, will wipe off with a damp sponge after firing. It prevents feet from sticking, but offers only a little protection against glaze drips. As you increase the EPK, the wash will better protect against glaze drips but will begin to stick to the shelf. Experiment to determine what formula best suits your needs.

2) Use “Setting Slabs” - clay slabs coated with kiln wash and placed under a glazed piece during firing. No kiln wash is applied directly to the shelf making rotation easy.
