The company recently extended its product range with the sale of clays from the Eifel, Upper Palatinate and Upper Bavarian regions. Witgert not only sells these raw materials, it also undertakes control of their quality and acts in a consulting and supervisory capacity with regard to their extraction, contributing its wealth of expertise from clay mining in the Westerwald. These clays are mainly plastic components for use in heavy clay ceramic products such as masonry bricks, roofing tiles, facing bricks, clinker bricks and pavers, plant pots, etc.
Another new product line are regenerated products, first in the form of clay filter cake from sand, coal and waste water treatment and second as chamotte from scraps from tiles, clinkers, sanitaryware, alumina porcelain insulators, etc. ground in all grain sizes and flours. Here the priorities are purity, availability and high-quality preparation. This enables the use of these materials in high-end products in the sanitaryware and refractories industry as well as fillers in non-ceramic applications. An increase in the grades stored at the Herschbach facility guarantees short-term availability.
