As a middle-sized family concern we have remained true to our roots for over 150 years.
We look back with pride on our long-standing tradition. Carl Friedrich Spiess, spurred on by family ties with Justus von Liebig, set up a business manufacturing clay earth pigments in Kleinkarlbach in 1861.
The company has remained in the original premises in Kleinkarlbach a further manufacturing facility has since been added in Alsbach-Hähnlein.
Today we are an established traditional concern for liquid and solid materials in the chemical and chemical-technical field.
Our experience spans 150 years, enabling us to offer our customers broad-based know-how in chemical production.
