I love marbling and would love to bring it into the classroom, but using traditional techniques of oil paints and turpentine can be very toxic and very odorous. I found a site that show s how to marble with milk, haven’t tried it yet. Watch this space as I will add more links to try out fresh ideas for marbling.
