Les Lawrence, who heads the ceramics department at Grossmont College in
San Diego, has been working with different methods for getting images
onto ceramic items. In a workshop, he told us that copier (and laser
printer) toner is about 30% iron oxide, and the rest is a plastic
material that melts and fuses the oxide to the paper. He said that he
was trying to get a toner recycler to fill the cartriges with other
materials, such as cobalt, manganese, ceramic stains, etc. I don't know
how that worked out. You might be able to track it down through the
