About Plainsman Clays
We are a clay mining and processing company in southern Alberta, Western Canada. We have select-mined clays specifically for pottery related uses since 1962 (in Montana, Alberta, Saskatchewan and Manitoba) and have knowledge and access to many other deposits. Plainsman mines thousands of tons at a time. We understand the deposits well, most of them are limitless, very consistent and produce raw clays that are balanced and very well adapted to pottery.
Technical Support & QC
We have a dedicated quality control and R&D lab to assure consistent products and it is ready to assist customers with development and trouble shooting issues. We were one of the first companies in the world to publish on-line data sheets and technical product information (in 1996).
Southern Saskatchewan is Clay Country!
The white layers partway down these hills are called "The Whitemud Formation". This geological formation dates to the cretaceous age, it is made up of marine sediments that are very clean and consistent. This is also dinosaur country, many fossils have been found in these layers.
Some quarries have many different kinds of clays, in layers one above the other. Below Melvin Noble stands in front of layers that may not appear much different. But our mining crews know how to separate them. In this case there are six types (averaging about 2-3 feet thick each). They are very different in both dried and fired properties (as demonstrated by the dried and fired test bars shown).
