Our history

"Quality for centuries"

18th Century

The first attempts to produce porcelain from local raw materials in the Karlovy Vary region and the beginning of kaolin mining.

19th Century

Porcelain production in the Karlovy Vary region expands. Small companies extract kaolin and are involved in its simple processing – competition grows. Kaolin is mostly mined by larger companies.

1892

Foundation

Successful kaolin mining in the Karlovy Vary region and a flourishing porcelain industry initiate the foundation of Zettlitzer Kaolinwerke AG.

1927–1938

Dynamic growth

The ever-growing company acquires more and more plants, particularly in Saxony. In 1938, it already owns nine deposits, ten washing plants, two brickyards, a coal quarry and a porcelain factory (Merklín).

1924

International standard set

Zettlitz Kaolin is declared a kaolin standard at the IUPAC Congress in Copenhagen. The trademark has survived all subsequent organizational and ownership changes.

1892–1912

Aquiring the competition

The company grows by acquiring small kaolin producers – Zebisch & Pfeiffer, Lorenz and Mottl.

1945

Nationalization

After the demise of the company as a consequence of the war, all kaolin mining and processing in the Karlovy Vary region is nationalized. Activity is recommenced by the national enterprise called Sedlecko–Vildštejnské Kaolinové a Hlinné Závody.

1950–1967

Back above the ground

Some of the mining takes place in underground mines. The company reorganization results in its division into seven production locations – the Sadov, Božičany, Hlubany, Skalná, Provodín, Střeleč and Sedlec mines. The company changes its name to Keramické a Sklářské Suroviny, Sedlec u Karlových Varů.

1972

Modernization

Kaolin production is modernized, and new products introduced to the market – plasters and paints.

It starts to manage the Únavov plant, PKZ – Užitková Keramika a.s., Poštorná, which specializes in the production of construction, chemical, garden and sewerage system ceramics, and the Třemošná plant.

1995

Tradition restored

The company is transformed into a joint-stock company and, as the direct successor of the original company, returns to its historical name of Sedlecký Kaolin, a. s. High-intensity, supra-conductive magnetic separation is newly added to the kaolin production process.

1990–1993

Privatization

Due to the political changes in Czechoslovakia, the company is divided into separate, independent (subsidiary) companies. In 1993, the company is privatized and renamed to Keramické Suroviny, Božičany, s.r.o.
