ST6040 Good thermal shock resistance Cordierite kiln shelf 600*400*18mm
1. Introduction
Selecting the right kiln shelves for your kiln use and application is important. Selecting the wrong shelves can be more expensive than you need or cutting corners can end up with ruined shelves after only few firings. When selecting shelves you will have three important choices: a) the material from which the kiln shelves are made, b) the thickness of the shelf, c) half size or full size shelves. To select the right kiln shelves you need to take into account your kiln type and style, firing temperature, firing type (e.g., oxidation, reduction, raku), glazing style used, firing frequency, ware weight and your strength. Once kiln shelves are selected and used, regular maintenance is required (kiln wash and reversing shelves).
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 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?”
