History of pencils

History of the Pencil core

Graphite (graphite) was discovered in the Cumberland Mountains of the Elisa Vèbes in 1564, England. In the beginning, the vein was dug up, and the improvement research was advanced although the graphite was only made a stick and it was used. In 1795, the France Conte invented the current underlying method of mixing graphite and clay. In addition, it has been discovered that the concentration of the core changes by not only grilling but also changing the proportion of the mixture.
