80% of all damage done to valuable art is caused by incorrect framing. Fact.
Paper is a very fragile product, and will break down if it is exposed to sunlight, moisture and/or acidic products. This is why it is vitally important that when framing, the correct products and techniques are used to protect it and slow down the aging process.
Beware – not all products that are sold as “acid-free” remain acid-free.
This is something that matboard manufacturers probably don’t want consumers to know too much about. The fact is, however, that any paper product made from wood pulp contains lignin, and lignin contains acid. To neutralize the acids, calcium carbonate or chalk is added to the product (this process is known as “buffering”) making it technically “acid-free” at the time of manufacture. What happens though, over time and with exposure to light, the chalk stops working, and the boards becomes yellow, brittle and acidic, causing “burn” marks on any valuable artwork it touches.
The only board to use, in my opinion, is museum grade 100% cotton Bainbridge Alpharag board. It is naturally acid and lignin free. To help protect your artwork further, from exposure to sunlight, we use as standard Tru Vue 99% UV Blocking Conservation Series Glass. Fluorescent lights emit UV rays as well as the sun, so it’s not enough just to keep artwork out of sunlight.
It never ceases to amaze me that people are happy to invest in valuable artwork, but then want to spend as little as possible on the framing. It just doesn’t make any sense to me, but that’s probably because I have seen the heartbreaking and irreversible damage caused by “cost cutting” when it comes to framing.
“The Age” newspaper recently published an article “Framed, and hung out to die” outlining just what a costly problem incorrect framing is becoming to our country’s cultural heritage.
Conservation framing protects valuable artwork. Yes, it does cost more, but isn’t it worth it?
