Galkyds and Liquin

[Sharon Knettell]

Alex,

I have used it in a turpentine wash to tone my canvas to get rid of the white when I am in a hurry.

Richard, any thoughts on that?

A good friend of mine has paintings he did ten years ago that have yellowed. He had used them primarily as a glazing medium.

Thanks again for sharing your thoughts Sharon.

Got your point about using the old, traditional materials Richard.

Wouldnt be fair to have this companies advertise AS WELL the flaws of their mediums?

Thanks again,
Alex

Fair perhaps, but highly unlikely. The folks who sell certain items (e.g. artist materials) have no vested interest in warning. Furthermore, it's important to recognize that simply because a company sells a product they may not be the manufacturers. Most linseed oil, for example, is made by one or two companies (Cargill, for example) and not by art materials companies. Unfortunately, alkyd resins have been shown to be problematic by the people who do make them.

Gary, that's for sure! It gets even worse. The folks who sell (and manufacture) art supplies all too often have no knowledge of the procedures and processes artist use, much less of the problems they are likely to encounter in the studio.

In fairness, the fact of the matter is that good results are the provence of the craftsman. Regardless of quality or appropriateness of application, there is no painting material that can't be misused to the point of failure.

Sharon, toning a canvas by staining is, of course, a very agreeable way to begin painting. Since I feel strongly that alkyds and traditional oil painting materials are not compatible, I do the same thing, only using a wee bit of black oil to promote drying and to be sure that dilution with turps has not compromised the binding of pigment thinned to that extent.
