Tom Norton Walnut Darkening Medium 42ml

Tom Norton’s Darkening Medium is an additive to be used to darken the original ink when a drawing needs that extra depth. 

Tom Norton Walnut Drawing Ink is made with artist grade pigments, not walnuts, and it is both lightfast and acid free! You will experience the rich walnut colour and superior rendering capabilities loved by the world’s most famous artists knowing that you are using an archival ink. In addition, most brown inks are shellac or acrylic based, which is fine for a myriad of techniques, however they dry permanent. Our ink acts more like a watercolour because it always remains water-soluble.
