Yeah, the main issue being that some of them didn't seem to realise that graphite is what they were _writing_ with, and they clearly could not have written anything with the galena samples. Carbon is light, lead is heavy. Sheesh. :-) *Considers* Maybe they _didn't_ realise that they were writing with graphite. The core of a pencil _is_ called 'pencil lead', after all... darned misleading terminology. :-P
