How to prepare canvas for longevity? (Rabbit skin glue?)

I would really like to make a painting that can be passed down countless generations through my family.

I heard that RSG (Rabbit skin glue) lasts long, but causes paint to 'crack'. On the other hand, I've heard that Gesso is good, but doesn't last long.

Maybe some other alternative?

What should I use? How many layers? If I did use something like RSG, should I still apply Gesso?

Thanks for help.

Priming and Gesso are Different Things

Gesso and the rabbit-skin glue are
different things, so your comparison
appears inane.
Rabbit-skin glue is the ground, i.e.
the initial layer (substrate), to protect
the raw paint surface: canvas, wood,
whathaveyou.
Gesso is the layer placed atop that,
amenable to the paint placed atop
it.
They're almost always used in unison.
The query, thus, makes almost no
sense; you're comparing apples and
oranges.
There is, however, rabbit-skin glue
vs. synthetic priming.

Animal glue is exactly what the old masters used it. Although "our" RSG from today might be a different product, it´s still ANIMAL glue. Like Ribera said, you can use the glue to prevent the oil to touch the fabric, preventing the oils to eat the fabric. The gesso would go on TOP of the dryed glue.

My recipe to make the ground is one part gesso, one part RSG and one part titanium white.

Works beautifully.

Oh yeah: and If you want to use something REALLY durable, you should consider doing a panel, and NOT canvas. Panels are much more reliable and sturdy than canvas.

Try to make a search on WC! with the term panel. You should find a lot of tips on how to build a good one.

I agree with Alex, however, I'm wondering here....

Do you already have an unprimed canvas? Is that why you are asking about the rabit glue?

I've seen PVA recommended to replace rabbit skin glue for size. Anyone able to comment on this?

Re: How to prepare canvas for longevity? (Rabbit skin glue?)

I thought panels warp over time, that's why I thought to go with canvases (perhaps I was thinking of panel-boards instead).

Many people seem to say good things about 'linen canvas' so I thought that was the way to go.

I don't have the canvas yet, but I am planning on painting very soon.

If panel is better than linen canvas, can anyone suggest what is a good type of panel? Are they more expensive than linen canvases? Do they still need priming/basing? What type?

Also, how does PVA-Size compare to RSG?

Thanks!

Guys, what do you think about this sort of panel:
http://www.westshoreartistpanels.com...ite-panels.htm

Quote:
The support is a thin archival aluminum composite material on both sides with a polyethylene core. With an 1/8" (3mm) thickness, it's thin and easy to transport yet extremely sturdy. It is also waterproof, which is great for plein air painting.

PVA sizing is a modern priming the old
masters lacked; brought us through mod-
ern science.
As Alex stated, rabbit skin glue was
employed by the old masters, however,
if something better comes along, we
ought employ it.
PVA, i.e poly-vinyl acetate is widely
respected.
If one must use only what the old
masters did, well, they did use rabbit-
skin glue.

I haven't heard of gesso (acrylic dispersion medium) not lasting long?
The conservators at AMIEN haven't got a problem with it.

Acrylig gesso can be used without sizing, that is , without rabbit skin glue or PVA.

Large panels often have bracing to keep them flat. Just like big canvases sometimes have bracing to keep them flat.
