Re: Roberson's Oil Painting Medium (vs Liquin)

Copper resinate Medium - attributed to Velázquez - One part verdigris (derived from copper - this material is substituted for the lead-based metallic driers), combined by cooking with 20 parts raw linseed or walnut oil.

I mixed one part of fir balsam with two parts of self-made basic copper carbonate powder. After a half of year this mixture became deep emerald green paste, very pure in color (and lightfast!).
Then I prepare a medium from this paste and sun-thickened oil 1:50, a kiwi fruit colored solution. It dries perfectly, and without odor during drying process.

Angry Re: Roberson's Oil Painting Medium (vs Liquin)

Does anyone know if there is an American vendor of Roberson's oil glazing medium? The formula for this medium given in this thread is similar to that on page 251of Ralph Mayer's Book, "The Artist's Handbook of Materials and Techniques, Fifth Edition Revised and Updated (1991)" that he sites as the best all round medium for painting and glazing . I would like to try the Roberson's oil glazing medium, but none of the companies in UK can ship it to me because of restrictions on shipping volatile items. I have searched everywhere (including google) for a vendor in USA, but cannot find one.
