Products - Kaolin, bentonite, sandstone
We process other silicate raw materials from high-quality kaolin mined in the Karlovy Vary area. Bentonite, kaolin, and sandstone are raw materials from which we create functional products using state-of-the-art technologies: cat litter and construction mixtures from bentonite, floated or fired kaolins for the ceramic and chemical industries, and many others. These natural and highly reliable materials are versatile in many industries including the production of porcelain, ceramics, paper, plastic, paints, rubber and more. Thanks to ecological processing, they are also suitable for use in cosmetics, pharmaceuticals, agriculture and water purification.
Offered raw materials
During mining, we try to process the available raw materials as efficient as possible. From the particular deposits we can obtain first-class kaolin, but also sand for construction and bentonite with high sorption properties. At the same time, we own a deposit near Mšené Lázně, where we obtain natural sandstone of pure color. We guarantee the highest quality of these minerals to all of our customers.

About kaolin
Sedlec la is the most well-known and oldest product made by Sedlecký Kaolin, a.s. It has been produced since 1892, when Zettlitzer Kaolinwerke AG was founded. Today’s Sedlecký Kaolin, a.s. is its successor.
Kaolin parameters
A product quality control system in accordance with ISO 9001:2000 has been in place since 1998. It exactly defines measuring and calibration procedures and methods. The quality control system certification provides customers with a very reliable guarantee of the given contractual parameters without any need to inspect the actual delivery.

Bentonite
Bentonite
About bentonite
Important activity of Sedlecký Kaolin, a.s. is the processing of bentonite and bentonite clays. Bentonite is a soft, fine-grain, inhomogeneous rock that particularly consists of a clay mineral called montmorillonite.
Bentonite use
In the construction industry, bentonites are used for casing suspensions, clay-cement mixtures, and drilling and insulation operations. Bentonites are added to concretes and plasters. Bentonite is used as a filler in the production of paints.
Other Bentonite use
Litter for cats and other small household pets to absorb liquids and odours is made of bentonite.
In the foundry industry, bentonite is used as a bonding agent for moulding mixtures.
Bentonites are also used in the food processing industry in, for example, wine or cider fining and beer stabilization.
The pharmaceutical industry utilizes bentonites as plastifiers in the production of ointments, pills and cosmetic creams.
In agriculture, bentonites are used as bonding agents in the production of feedstuff, composting and soil fertilizing.
Bentonites are added as plastifiers in ceramic mixtures.

About Natural Sandstone
Natural sandstone is mined from a deposit owned by Sedlecký Kaolin, a.s. in Mšené Lázně by Mšenské Pískovce, s.r.o. The mining is conducted using pressurised water directly in the sandstone deposit. The sandstone is subsequently processed with diamond saws or, for stonemasonry processing, by hand.
Sandstone look
The Mšeno sandstone is a natural rock of a pure colour, appreciated for its decorative characteristics. It is used for sculpting, renovation of monuments, and garden and interior architecture (such as St. Vitus Cathedral, Charles Bridge, Libochovice Chateau, Prague Botanical Gardens etc).
