Koh-i-Noor Hardtmuth Factory
Koh-i-Noor Hardtmuth, based in České Budějovice, is one of the world's oldest and most prestigious manufacturers of writing and drawing instruments. The company was founded in 1790 by Joseph Hardtmuth in Vienna, moving its production to Southern Boemia in 1848. The firm achieved global fame by inventing the modern pencil lead from a mixture of graphite and clay, which revolutionized the grading of pencil hardness. The name "Koh-i-Noor" refers to the famous diamond and was introduced in 1889 following the success of the iconic "1500" yellow pencil. Today, the company exports its products, including artist paints, chalks, and accessories, to over 80 countries. The factory is not only a symbol of Czech industrial tradition but also a globally recognized trademark for quality in fine arts and technical drawing.
