Our History

The history of the HOFFMANN MINERAL company is, above all, the history of one family. The story of four generations who have given themselves to the mining and upgrading of a special raw material: Neuburg Siliceous Earth (Neuburger Kieselerde), today mainly known under the trade name of SILLITIN, in previous times also called "Kieselkreide" (Siliceous Chalk), "Kieselsaure Kreide" (Silicic Chalk), "Neuburger Weiss" (Neuburg Whiting) or "Neuburger Kieselweiss" (Neuburg Siliceous Whiting). During the over 100-year span of company history, many things have happened. A great deal has changed over the years, but some characteristic features have remained as ever before.
