Material Notes:

Dunn clay is a selection originating from our Gleason, TN processing facility and is characterized by moderately high levels of kaolin interspersed with the presence of some carbon content. It is an economical selection of clay that can be considered particularly where high volumes of clay may be required. The selection has an established history of performance in pavement sealer applications and structural brick compositions.Information provided by Old Hickory Clay Company
