Vegan art supplies can be hard to find, so I want to make it easier with this list. Art supplies have traditionally used many animal ingredients. Paints, mediums, and even papers may contain bone char, gelatin, ox gall, rabbit collagen, eggs, carmine, and shellac. Natural paintbrushes are made from the hair of sables, pigs, and squirrels. Many higher end art supply companies use animal ingredients because these companies have been around in some cases for hundreds of years and use traditional recipes. But traditional doesn’t necessarily mean better. As you’ll see in this list, vegan art supplies are available in both student and professional grades. Contact art supply brands to double check vegan status, or just let them know you’re looking for vegan products and don’t stand for vague answers.
