Galkyd Lite & OMS 50/50. . .

[Chris Saper]

Richard,

I will be in that workshop! Look forward to meeting you!

[Richard Bingham]

Chris, what a wonderful surprise! I was hoping to meet you. Knowing a couple of the folks who will be in the workshop, it will be like old home week!

Just a note.

I have a friend who is a floral painter among others. I told him about Galkyd and Liquin. He is really sorry he has used them as they both yellow.

I think since a lot of portrait work is done on commission we don't see many of our paintings ever again and we don't see this result. He has paintings he did years ago for comparison. This of course is anecdotal and not scientific evidence (so my scientific professor husband tells me).

He has pointed this out to me. All plastics ( acrylics whatever) yellow with time. If you have ever seen an acrylic window exposed to light over time you will see that it yellows.

His credentials on request.

Thanks for that , Sharon. Unfortunately, where the durability of painting techniques is concerned, all observations/information end by being anecdotal from the scientific point of view. This is owing to the fact that the self-same materials handled differently by different people, in different combinations produces an infinity of results without any standard of controls by which to compare them.

There's enough hearsay, misuse, and controversial strife over painting materials that have been in use for decades and centuries, Which is the reason I feel it's so unnecessary to go looking for a "magic bullet" without any "lore" to support its use. For anyone who insists only modern synthetics can produce effects they "need" to make their paintings, I'll guarantee the problem has already been solved . . . in most cases, hundreds of years ago!

There are so many permutations of synthetic materials around, I'd be foolish to state this as a fact, (not having recently examined them) but I don't believe acrylic chemistry is employed in the forumulation of either Galkyd or Liquin. (???)

FWIW, as far as automotive coatings are concerned, acrylic chemistry clear coats and paints in general are an improvement over alkyd resins.

[Michele Rushworth]

I agree with Richard: why tamper with a proven method? Linseed has been shown to stand the test of time. I myself have had delamination problems with paintings containing an alkyd, too. I used Liquin and will be reluctant to ever touch the stuff or use any other alkyd mediums again.
