Antique Oil Painting of Old Time Circus Requires Tricks for Cleaning

 

I want to show this picture partly because its a very interesting painting and partly because you might enjoy hearing about kind of a strange way of cleaning a painting. Cleaning is part of the art conservation/restoration process but it is usually not an essential part of the preservation process. In other words, a yellow varnish is usually not the cause of a painting falling a part. But, it can be, or course, the reason the painting doesn’t look anything like what it did originally. A dirty painting surface can have a huge affect on the aesthetics… and art is all about aesthetics, right? Don’t agree? Leave a comment…



 Hard varnish results in not the usual cleaning techniques

Cleaning a painting - Hard varnish results in not the usual cleaning techniques



When we estimate a cleaning, we do special tests to see what dissolves the varnish or grime or whatever (the variety of types of layers we find are many!) and make sure that those solvents DON’T dissolve the original paint… at all! We’ll sometimes, we’re suprised to find a varnish that won’t dissolve!

This very cool 19th century painting of a European circus had been cleaned before but, it seemed obvious, that the previous restorer simply wiped the surface and gave it new varnish because he did not try and remove the yellow varnish… which is very hard.

In fact, it took a fairly exotic recipe for a gel to get the varnish to move. But the problem was that the gel was too strong for the removal of the varnish in areas of dark paint; the dark colors were sensitive. Turns out that we had to break or scratch off the hard varnish instead of dissolving it. Turns out too that the dark areas of paint seemed kind of “cloudy.” So the removal of the varnish allowed the dark colors to really saturate and get a deep color when we applied the new varnish. The transformation was gorgeous.

If you are not “into” looking at paintings, this is probably boring stuff. But its really good info for painting collectors and curators who wonder about the in’s and out’s of estimating the cleaning of paintings.

Just to show you that this wasn’t a freak case, here’s another case that’s in the lab right now: A German painting of lovers from which the varnish came off in large scales and flakes as we broke it off the surface.



Hard varnish flakes off. What is it?

This varnish could not be dissolved.



Was this a "permanent varnish?"

Was this varnish meant to be so hard that it would be a "permanent" varnish? "Permanent" anything in art conservation is NOT a good idea.


So, how long does it take to clean an oil painting? How much does it cost to clean an oil painting? Both questions that I hope you can see is not a question to be answered without testing and experience.
