Laser/photocopier toner is a powder comprising essentially a wax and a finely ground pigment. I would be VERY surprised if black toner contained anything reprehensible, as the pigment is essentially carbon black, which is produced industrially by the condensation of sublimed carbon produced by burning a hydrocarbon with insufficient oxygen to ensure complete combustion (e.g., the black deposit on the chimney of an oil lamp with too much wick exposed). Coloured toners may be different, but I doubt whether pigments like cadmium yellow or litharge would be used, as grinding them would be a very hazardous process. I would also be very surprised if the wax could contain any RoHS-designated substances, either. But have you thought about the label itself or its adhesive? :-) :-) Brian Dion, Mario wrote: > Bonjour TechNeters, > > Here is a question about RoHs.
