Conserving old master drawings: a balancing act
A fundamental role of a museum is to care for its collection and preserve it for future generations.발음듣기
European drawings from the 1300s to the late 1800s or old master drawings- are particularly vulnerable- they are on paper and hundreds of years old.발음듣기
This makes it easier to see the marks left by the wires of the paper mold; stains; a watermark; a tear- with a darkened area that shows where it had been previously repaired; and at the corner, the shadow of the piece of paper that had been used to attach the drawing to a mount.발음듣기
Now, the conservator tests the solubility of the ink to ensure it won't bleed during treatment.발음듣기
She places the drawing on a vacuum table, a device that extracts the liquids used in the treatment, out of the paper.발음듣기
She uses this small brash to apply an ammoniated water solution to reduce the brown "foxing." This solution subtly releases the color of the foxing, which distracts from the appearance of the drawing.발음듣기
She carefully alternates the application of ammoniated water with that of ethanol, in order to reduce "tide lines"- irregular lines or blemishes left behind as the ammoniated water solution dries.발음듣기
Wearing magnifying lenses, she examines tears and prepares them for mending and reinforcement.발음듣기
She takes the piece of Japanese tissue and carefully applies wheat starch paste to mend the tear.발음듣기
Japanese paper has very strong fibers, is chemically neutral, and can easily be identified and removed.발음듣기
She allows the paste to set by putting the drawing between blotters and weighing it down with glass blocks and weights.발음듣기
To complete the conservation treatment, the entire drying is humidified and then placed under weights with blotters to remove the moisture and flatten it.발음듣기
This process extends over a two-week period and the blotters are repeatedly replaced to facilitate drying.발음듣기
Rather, it's to safely reduce the damage that distracts from the design and bring the sheet closer to the artist's original intent.발음듣기
