ceramic kiln stilts,
Benefits such as high thermal conductivity, low mass, light weight, stability (i.e., no warping), and resistance to glaze sticking and penetration have gained these kiln posts increasing acceptance from artists, educators, production potters, and tile manufacturers. Despite their popularity, questions are often raised regarding the appropriateness of the shelves’ use in resistance element electric kilns. Specifically, “Are they safe to use in my electric kiln?”
While it is true that some forms of silicon carbide are specifically designed to conduct electricity (such as heating elements), the internal bond matrix—and especially the glassy, oxide layer that is intentionally fired onto the surface of kiln posts—dramatically lowers their electrical conductivity compared to other types of silicon carbide kiln posts. As a result, the electrical conductivity value of kiln post is low enough to be considered safe for use in top-loading electric kilns.
In addition, as the kiln post are fired repeatedly in an electric kiln’s oxidizing atmosphere, the glassy layer continues to accumulate and further reduces the rate of conductivity. The use of cordierite or similar post compositions also eliminates the possibility of current being conducted from one level of shelves to another, should element contact occur on a lower shelf.
