Saponification in art
« on: September 14, 2014, 08:15:56 AM »
I was reading the wikipedia page on saponification and noticed a section at the bottom:

http://en.wikipedia.org/wiki/Saponification#Saponification_in_art_conservation

Oil based paint with heavy metal components can over time convert the oils in the paint to soap, which is a conservation issue for older paintings.

I never knew that :)

I've noticed some of my Constables trothing around the edges!

It's something to bear in mind.  I'll have to carefully inspect the Monet collection in the west wing.
