Does Porcelain Stick to ADVANCER® Shelves?

Due to the high amount of flux used in porcelain clay bodies (up to 50% typical) to achieve translucency, it is not uncommon for porcelain clay bodies to stick to the ADVANCER surface. The higher the firing temperature is, the greater the opportunity for the flux to interact with the oxide glass layer of the shelf. Pieces with trimmed foot rings supporting larger pieces, like bowls, tend to stick more tenaciously than broad, flat bottomed pieces due to increased pressure on contact area. Some cone 6 porcelains may not have a sticking problem on ADVANCER. Please contact us for more specific information.
