Graphite base products are a very traditional product of KOH-I-NOOR HARDTMUTH a.s., with history dating back to 1790.
The combination of basic raw materials – low-sintering soft clays and pure, modified ground graphite powder and its complex homogenisation creates a mixture for the production of 20 gradations of graphite leads, with the scope of 8B to 10H. Soft gradations are marked with the letter B taken from the word “Black” and hard gradations are marked with the letter H, which comes from the word “Hard”. There are two gradations between these two groups marked HB (HardBlack) and F (Fine).
