The true quality of kaolin is measured not only by its chemical composition, but above all by its stability over time.
As early as 1924, our Sedlec Ia kaolin was declared the international standard at the IUPAC congress in Copenhagen, confirming our role as a global reference point in the industry. For industrial partners, the raw material must meet identical parameters in every delivery, from the production of fine hotel porcelain to technical ceramics.

At Sedleck&yacute; kaolin, we rely on a quality management system according to ISO 9001 and ISO 14001, which precisely defines procedures from extraction to laboratory output. Our standard is consistency, which saves costs and eliminates risks for our partners.
For us, quality is the result of a system we have been building since 1892. 💙
