M.Graham watercolors are created with exceptional amounts of pigment in a time-honored binding medium of pure gum arabic and natural blackberry honey. As an essential ingredient in our binding medium, honey contributes to moistness for smooth, easily controlled applications, increased pigment concentrations, and freedom from over reliance on preservatives. Because of the honey medium, our watercolor resists hardening on the palette, or in the tube. It dilutes easily, often after months of disuse.
