Customer Reviews
This is the first time for our cooperation. They are indeed what we want. We look forward to working with you again in future.

—— Fred (USA)

Your ceramic tube is really good for our application, we will buy more in future.

—— Jessica Ferrara (Italy)

You are the best, your ceramic parts are perfect

—— Dalibor(Czech)

Our client satisfied with the Cordierite kiln shelf and sagger . But It would be better if the delivery time be shorter in our next order.

—— Van Nguyen (Viet Nam)

I hope you are fine and business is well. We recieved the perfect goods from you, your are the best.

1. Introduction 

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 shelves 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 Advancer shelves—dramatically lowers their electrical conductivity compared to other types of silicon carbide kiln shelves. As a result, the electrical conductivity value of  kiln shelf is low enough to be considered safe for use in top-loading electric kilns.

In addition, as the shelves 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.
