They are oil paintings with an acrylic gesso.
Didn't realize it, but it has been since high school! which was the mid seventies!

Easy Oil Painting Techniques by Delmus
Good to hear. I have one oil painting from the late seventies (*^&% yep gettin old) Most of the other art is acrylic. I'm getting back into painting with oil and was curious about the painting's longevitty. I'm debating on using an oil primed canvases moving forward since the gesso bases is more absorbent. Of course oil primed is more expensive ... I was wondering if you added in any matte medium to the gesso when you primed it.
I personally think acrylic gesso is just fine! I also have a bunch of old paintings I did from high scool (not 40 years but more like 25ish) that were on just cheap old pre-primed canvas that look just fine. Turn them over and some have some seepage of oil into the cloth weave but it's not terrible. They still have decades of life in them assuming I don't store them dumbly.

I went to the art museum today and had a really close look at many paintings. I've noticed that overall the oil paintings were actually in pretty good shape. I guess having a conservator and climate control helps. I looked at Dutch paintings made in about the 1700 and all of the oil paintings on wood were phenomenal - hardly any cracking whatsoever. The paintings on canvas had miniscule cracks that were hardly noticeable unless your inches away. Of course the paintings during this time were small and tightly rendered.
I checked work of landscape artists from about 1830-50 and again pretty decent quality. One large painting by John Frederick Kensett 1854 was immaculate. What did he do!? It was perfect. Chase had a couple of large paintings with nearly no cracking. If anyone has a museum nearby I'm wondering if Chase's other paintings are in such good shape. Two VanGogh's painted on fabric were also in good shape even though he used thick paint. I noticed that one spot where he use thick ochre had some cracks of course this was the thickest area of paint - about 1/8"
I saw one Sargent and I must say this painting was amongst the worst. Another painting by Lee Krasner that appeared to use thin dark brown paint over thicker paint had quite a bit of cracking.
i noticed that thick light colored/white paint cracked the worst. I also noticed that many darks also had cracking. I closely checked midrange colors and they seem to hold up the best.
Other artists with paintings in superior condition were Tarbell, John Sloan, and Emil Carlsen. The museum is under renovation so much has been in storage, but it was still worth taking a look.
One thing I found interesting thought the Dutch works on oil were immaculate many of the newer paintings on panels had more cracking. I wonder what was different/
Just found this post so may be way out of date.
But some studies suggest Zinc White is a problem in paintings done in the last 200 years. If Zinc/PW4 is in the painting ground or in the oil paints its causing the delaminations...
It seems this is making it hard to determine whether oil ground or acrylic ground works best as Zinc white "contaminates" both oil and acrylic.
My question is the stability of the Rabbit Skin Glue because swells with humidity...and thats why many painting on linen crack...
Golden also has a good article: Using Oils with acrylics...
I am interested in painting on primed loose canvas (so that I can easily roll it up and store it away once the painting is finished). I work large and think it might be handy to paint with acrylic directly on the loose canvas. My question is this: If I finish a large-scale painting on primed, loose canvas, can it be presented this way in a gallery, or would it need to be then stretched on stretcher bars or on a board? If so, is there any issue with the primed canvas not stretching enough, etc? It appears that painters like Pat Steir paint this way, but I am not certain. Any thoughts?
I paint this way on loose canvas when I am experimenting. I tape onto hardboard. Once dry I stretch onto bars, what I have noticed is that when I stretch the canvas onto the frame, sometimes the paint will crack. This has only ever been very minor in my experience and is easy to touch up.
I imagine the longer it is left, the more likely it will crack-this is worse in oil paint than acrylic and it is the balance of stretching before the film is hard, but after it is dried enough.
I have seen work presented in a gallery on loose canvas, but it has been hung with metal rings and nails, like are used in shower curtains and tents,. Hence the work had a flag like appearance.
Hope that helps
I have oil paintings from the 60's when I was in art school that were primed (by me) using acrylic gesso and they are all fine.
