M-23 is produced from the Old Hickory Gleason TN processing plant. It is a highly suitable grade for low fire white firing compositions as well as stoneware and high fire porcelain ceramic bodies. It has very low levels of residue contaminants and especially carbon content. The high kaolinite value and low iron and titanium help provide exceptional fired brightness and the fine particle distribution offers excellent plasticity to ceramic formulations that are even marginally low in ball clay content.
