Sorry for the complete randomness of this post.
Our office got a new Xerox printer that is Eco friendly. The "ink" is wax instead of toner powder. The waste is just a small black wax block that could be melted into crayons. It will write on paper just like a crayon.
I printed off a few mini stained glass designs on overhead transparencies. The cool thing about the ink is it leaves a raised surface so I think this will work to my advantage for coloring. If I get a chance this weekend I'll paint a few with Gallery Glass and take pictures.
