This M. Graham Artists' Watercolor Paint, Viridian is formulated from Hydrous Chromium Sesquioxide (PG 18).
M. Graham Artists' 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 M. Graham Artists' Watercolor binding medium, honey contributes to moistness for smooth, easily controlled applications, increased pigment concentrations and freedom from reliance on preservatives. Because of the honey medium, M. Graham Artists' Watercolor resists hardening on the palette, or in the tube. It dilutes easily, often after months of disuse.
Available in 15 ml. tubes.
