18" x 28" x 1/2" (457 mm x 711 mm x 13 mm) oxide bonded, silicon carbide shelves (dark grey) are coated on one side with a high-alumina kiln wash. The design incorporates side slits to prolong shelf life by relieving thermal expansion stress. Typical properties and composition are listed below.
Cutting charge $2.00/inch. Larger jobs quoted.
