Icart was most popular in the 1920s and ’30s. At the time, it was fashionable to give a gift for a wedding or special occasion, rather than money. What better gift than an Icart etching? They were beautiful, signed by the artist, limited edition, and reasonably priced, most in the range of $15-30. The sellers of the art, mainly art galleries and department stores, were not interested in the art as investment, so they were expedient in framing.

What was done that was expedient? The worst offense was to use glue. Loose sheets of paper do not usually lay flat when framed, especially in humid areas. So the problem was solved by gluing the paper to a board, usually with horse glue. Most times the etching was also framed with a mat in front that was frequently glued to the etching.

The second problem is acidity. Paper is naturally acidic due to the acid in pulp, mainly tannic acid. Over time cellulose fibers in the paper break down and add to the acidity. The framer’s offense was to use acidic mats and back boards in framing the etchings. These materials were in constant contact with the etching, allowing acid to leach onto the paper. All of these acid sources contribute to the problem. The acidity causes the paper to weaken and degrade, making it brittle and yellow and eventually destroying it.

The third problem is called light darkening. This is the process by which an etching darkens when struck by sunlight, getting worse year after year. Sometimes the darkening is so severe that it’s difficult to make out the image, but that’s rare. Usually there is slight to moderate darkening.

The last problem is called foxing. This is usually (but not always) caused by fungal or mold growth on the paper, aided by high humidity. It shows up as brown spots.

Can anything be done about these problems? Tune in tomorrow for “My Icart etching doesn’t look good. What can I do about it?”
