*What exactly is the degree of hardness?

To better understand the degree of hardness of a mine, you must first know that a mine is composed of graphite (which provides coloring) and clay (which gives solidity).

The mixing ratio of these two materials will determine the degree of hardness of the lead. The greater the amount of clay, the harder the mine will be. Hard mines offer a lot of accuracy and durability, but lack blackness. They can also dig into the paper if pressed too hard. Oily leads provide good blackness, but wear out quickly. They are sometimes difficult to erase.

The letters on the mine packets symbolize the category of mine it belongs to:

H: Hard

F: Fine

HB: Hard Bold

B: Bold

E: Extreme

Then the numbers, ranging from 2 to 9 , offer an indication of the degree of hardness of the mine. For example, a 9H lead is very hard and a 9B lead is very oily and soft.

HB mines are the most commonly used.

Faber-Castell is one of the largest manufacturers of writing instruments and office accessories. He is also one of the oldest

— it was created in Stein, near Nuremberg, in 1761, by the carpenter Kaspar Faber, his wife Maria and his son Anton Wilhelm.

At that time, the company was called AW Faber Company and it was only in 1900, when the granddaughter of Johann Lothar Freiherr von Faber (the great-grandson of Kaspar Faber), married a Count of Castell, that the company was renamed Faber-Castell.
Today, Faber-Castell is still a family business synonymous with excellence.
