Lead (Pb) has NEVER been used in pencils. When they first discovered graphite, they thought it was some form of lead and called it “plumbago” (Latin for “lead ore”). The black core of pencils is still referred to as lead, even though it never contained the element lead.

Also graphite is a (weak) conductor of electricity. Although I’m not sure if this has anything to do with HB pencils being recommended by CB.

IDK why we’re having a discussion about pencils lol but whatever… :P
