- Family: Ball Clay
- Region: North America
- Mined At: Unspecified
- Raw Mineral: No
- Generic: No
Notes
This Gleason, Tennessee material has been used in the electrical porcelain and tile industries for many years. It has a finer particle size than many other K&T Ball clays and is thus more plastic and prone to drying cracks. However, its added whiteness and low coal and other particulates make it an attractive material.
