This is kind of what I thought when I first read this. I think the only reason CGC put in MC paper was so they could tell you you needed to change it out every 7 years. I think CGC actually thought this would be a kind of CPR revenue stream for them, since comic collectors are so anal or have a self-imposed disease like OCD. If you started in 2000, you'd be on your 3rd slab per book by now, right?
Thank god comic collectors weren't stupid enough to fall for this, as it's been proven to be marketing bullshit.
It might sound crazy, but so did CGC wanting to call Modern books "Wizard Age". When it comes to greedy ideas, I don't put anything past CGC.
An excerpt from their site:
Note: It is best to replace these sheet every few years, to avoid toxin feedback. Sometimes you will see shading on the sheets over time, which is the toxins bleeding on the Micro Chamber paper from the comic. A Micro Chamber sheet can only hold some much waste and you don't want polluntants to bleed backon to your preservation project over time, so just check the sheets and replace them as needed.
"I don't know where they are getting their use of the term "saturation point". There is a limit to how much acid, microchamber paper can absorb. However, that limit is approximately 170 times that of the equivalent buffered paper. But there is no point where MCP will suddenly release all of the pent up pollutants, oxidants and acids they have absorbed throughout their life. It won't bleed back onto books. "http://boards.collectors-society.com/ub ... 11&fpart=5
"I think there is some confusion here.
The page you referenced above is NOT from CGC
The "Collectors Society Member" badge at the top of their website is NOT an endorsement by CGC. Every free member of the boards, journals or registry is a Collectors Society Member. You can get your own badge to put on your website Here
The statements "avoid toxin feedback." and "you don't want polluntants to bleed backon to your preservation project" are indicative of a lack of understanding of how microchamber or for that matter any alkaline paper (such as fullbacks) works to preserve your comics. They simply have no basis in scientific fact.
Ink transer does not significantly diminish the pollutant/acid neutralizing effectiveness of microchamber paper.
NONE of those statements were made or endorsed by CGC. It is just part of a website that two guys put together. And if spelling or grammar are any indication .... "
I know Nathan. They were just trying to put together a website that pulled in a variety of sources of conservation / preservation of comics. Nothing to do with CGC. You'll note nothing is sold on the website and there are links to places that do sell and to people/businesses that perform restoration.
I doubt my research has been exhaustive, but the only places I've found that speak strongly about Microchamber papers archival benefits are places that also sell it. As I said before, more neutral type sites talk about it being effective in removing odors. For instance, I earlier linked to the North East Document Conservation Center and did so because the Library of Congress's website mentions them for paper conservation. I cannot find any reference to microchamber paper on the Library of Congress's website. They do talk about conserving paper documents of course, but nearly always in terms storage conditions or changing the PH of the paper itself.
conservationresources.com (company based in the United Kingdom) is very big on MicroChamber paper and has tests to back up it's benefits. I'm not qualified to say if the tests are fundamentally sound. However I can see that the tests all are designed around introducing large amounts of pollutants into a sealed case, artificially aging the paper and then doing fold tests. But these tests don't seem to mimic real world conditions. - collectors don't intentionally store their books in an environment that is artificially polluted and hot. For our purposes, the microchamber paper is mostly just absorbing outgassing of the paper itself. If collectors are showing any good sense, the books are already stored in temperature, humidity and light controlled environments. Things that the Library of Congress stresses. You would basically have to store your books in a diesel mechanics garage during a hot Florida summer to duplicate the test conditions. conservationresources.com sells microchamber paper.
I think it's 100% accurate and safe to say that MicroChamber paper will not do any harm. The debate has always been just how much good it really does.
