I thought pencil manufacturers actually use graphite. From the article I understand that graphene pencil is only useful to write on steel sheets.

- jerf 15y agoI had been led to believe by previous articles such as [1] that graphite contains graphene, albeit in small quantities and not in a useful state. The process of trying to produce a link to substantiate this has left me less sure whether it "contains" graphene, or if it merely can produce it under the circumstances described in the article. Given what it is and how much carbon gets around on this planet, it is perhaps hard to say what "contains" graphene in the first place, in much the same way I'm often a bit annoyed when someone counts every oxygen and two hydrogens anywhere in a compound as "water", regardless of how tied up they are.
