Talk:Rabbit-skin glue

From Wikipedia, the free encyclopedia

it would certainly rock quite nicely if someone were to beef this up with a description of:

1.) how it's used
2.) it's history
3.) pro's and cons vs. other primers

I would write it, but there's a good chance I would slide the phrase "it would certainly rock quite nicely" somewhere in there.

[edit] archival properties

I removed the unattributed claim that oil paint will eventually delaminate from acrylic gesso. Where did that come from? I no longer like the stuff, but I've got oil paintings I did on acrylic gesso 45 years ago that are in perfect condition. —The preceding unsigned comment was added by Jive Dadson (talk • contribs) 05:57, 14 April 2007 (UTC).

I disagree with your removal of this information. I am the original author of that information. I read it in an authoritative book on the chemistry on painting. I will try to find the original citation. Once again, we need people to stop using their own anecdotal evidence of something as a justification for deleting information. In the book I read--and forgive me for not right now having the citation--it had a clear chemical explanation why the delamination occurred. Rabbit-skin glue is porous and oil is able to penetrate that surface to form a permanent attachment. Because of the chemical qualities of acrylic gesso--which is not porous--oil paint is not able to form chemical bonds and therefore cannot form a permnanent attachment. I am restoring the section and will seek out the book for citation. User talk:Curmudgeon99

I further disagree with the edit that removed the point that oil-based primer can take weeks to dry. Having made hundreds of canvasses myself using rabbit-skin glue and oil-based gesso primer, I can personally attest that it does take weeks. I am restoring the original. User talk: Curmudgeon99

  • It can take weeks to dry. It can also take mere days. This is an article on rabbit skin glue; not on the drying times of oil paints. There are many factors that can affect the drying times of oil paints. Thickness of application (of the oil paint) is one factor: thin coats dry more quickly. The ratio of oil to pigment matters. More oil results in slower drying times. The choice of pigment matters. Zinc white is a fairly slow drier; lead white dries more quickly. (Titanium white falls in between.) The choice of oil itself can be a factor. Many paints, especially light colors, such as white, use less "yellowing" oils than linseed oil, and this can slow down drying times. The addition of other pigments (especially one of the umber pigments) can speed up drying times. Environmental factors matter too. Why not just note in the article that oil paint dries slowly, and leave it at that? That simply distinguishes it from acrylic paint, which dries much more quickly.

Just as a final note to this discussion: since I provided the original source for the point that oil paint eventually delaminates from acrylic gesso [The Painter's Handbook] and that you have not chosen to refute that point, I am taking that as an acceptance of the fact that oil paint is not appropriate for use on top of acrylic gesso. I consider this point to be sourced, cited and done with. —Preceding unsigned comment added by Curmudgeon99 (talk • contribs) 12:28, 14 September 2007 (UTC)

[edit] Bookbinding

Rabbit skin glue is commonly used in book binding. I'll revert the last edit and reference it (prob. the Thames & Hudson Manual of Bookbinding) when I have a moment.
