«I had first seen the Jabach family portrait in a warehouse in London over a year ago and loved it, but I'll admit that when it finally arrived in our paintings conservation studio at the Museum this past June, I was a bit overwhelmed—it's enormous! Fortunately, the work's current condition needs to be fully documented before conservation can begin. This not only helps a conservator understand the painting and its issues but also provides some breathing space and thinking time.»
Once Met photographer Juan Trujillo carefully recorded the front and reverse of the painting, I began to examine the layer of varnish covering the work. It's very discolored and definitely not original; it was most likely applied at either the end of the nineteenth century or the very beginning of the twentieth. A varnish is a key component of paintings from this period because it fully saturates the colors and reveals the complete tonal range, which is vital to all the pictorial effects of space and volume that the artist created. When the varnish oxidizes and severely discolors—as it did in this case—it does just the opposite, distorting and deadening the colors and substantially reducing the tonal range. That's why we take it off.

Following tests to establish a safe and effective way of removing the old, discolored varnish, I began the process of cleaning the work. It's extraordinarily well painted and generally in great condition, so this is very exciting and rewarding. In the following photographs, you can see how the removal of the dark, yellowed varnish reveals Heinrich's pink toes as well as Charles Le Brun's assured painting technique.
