The Wrenshall, Minnesota area has a long history of clay production and
it appears there are still abundant clay resources remaining in the area.
Wrenshall is located eight miles southeast of Cloquet, Minnesota, and 20 miles
southwest of Duluth, Minnesota . The production period in the Wrenshall area was
1882-1953, and the products produced were primarily brick and clay tiles.
Because of the productive history and the potential resource available, the
Natural Resources Research Institute (NRRI) of UMD became involved in a study
to determine the feasibility of using Wrenshall clays in the manufacturing of
clay products. This study includes the determination of the physical and
chemical properties of Wrenshall clays, the development of a clay products
inventory, and a products-property match analysis.
The objective of NRRI's study is to aid the development of a viable clay
products industry in the Wrenshall area. This report describes some initial
results, provides a preliminary assessment of Wrenshall clays and outlines a
plan for further study .
