This may be due to the lack of information published about these oils in artists' manuals and not taught in art schools. This article provides an introduction to the many different drying oils (in this case, these are all derived from flaxseed) available to the industry and now to artists through Natural Pigments.

    Silverpoint is rarely used today except by a few persons who take an interest in traditional artists' materials, yet it was a favorite technique of the old masters.
