Clay manufacturing can be either via a dry or wet/slurry process. Manufacture is comprised of a number of phases; extraction, blending (where necessary), crushing and drying. Each stage requires certain competencies and machinery to ensure that we always offer the most optimum product for each application. Clay is tested regularly throughout the manufacturing process to ensure

Evidence of Ohio's Glaciers

The process produces a fine-grained powder of silt and clay— glacial flour —that is picked up by meltwater streams. Since the particles are so fine, they are slow to sink to the bottom, remaining suspended in the water column instead. When sunlight hits the water, these particles absorb the shortest wavelengths: the purples and indigos.

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

Sediments directly deposited by glacial ice are made of a combination of clay, silt, sand, pebbles, and even boulders. This type of deposit is called glacial till, or simply till . Till is the unsorted sediment created when ice picks up, transports, and directly deposits the sediments in another location.

Slope stability analysis of a fissured glacial clay

Clay straight from the ground does need to be processed. The clay will need to be sieved to remove unwanted material such as rocks, twigs, and roots. Sieving can be done either of two ways. The clay can be pulverized when dry and then sieved, or dried, slaked down in water, then sieved.
