Miscellaneous
- Family: Kaolin
- Region: North America
- Mined At: Unspecified
- Raw Mineral: No
- Generic: No
Notes
Pioneer clay is used in pressing, casting and extruding bodies. Its fires fairly white and provides moderate to good dry strength. Its chemistry is very close to theoretical kaolin.
Pioneer Kaolin has been a standard for many years in the North American ceramic industry and bodies and glazes.
