Gum Arabic
Filed under Art History
I enjoyed the story on NPR this morning about gum arabic. I knew about the artistic uses, but didn’t know all the food products it’s used in.
From Wikipedia:
Gum arabic is used as a binder for watercolor painting because it dissolves easily in water. Pigment of any color is suspended within the gum arabic in varying amounts, resulting in watercolor paint. Water acts as a vehicle or a diluent to thin the watercolor paint and helps to transfer the paint to a surface such as paper. When all moisture evaporates, the gum arabic binds the pigment to the paper surface.
