    I've done it with graphite from pencils before. The clay didn't seem to cause any problems. I used a piece of graphite from a pencil as an electrode to coat a wire in platinum for use in a fuel cell...it worked just fine right out of the pencil.

    Isn't coal a relatively pure allotrope? I dont think you need it that pure anyway, pure graphite is brittle and I've never heard of electrodes being that way. So I would say the pencil would work also.

    maybe you can go ahead with penil lead for electrolyles, the additives in lead will not affect your electrolysis .
