Just learned something new about PVC holders today.

As a coin collector I am well aware of what PVC can do to a coin. I just learned something new about PVC that I was not aware of.
Today I took some of my paper/cloth space items to a conservationist/preservationist (recommended by the De Young museum), to "neutralize"/preserve various paper items before they get put in picture frames etc. I brought the items to her house in the PVC "sleeves" they were placed in by the auction company that sold them. She mentioned to me that PVC can screw up paper that you wish to preserve. In some cases it can "strip" the ink off of the paper if it is in contact with it for any period of time. She recommended that any paper items one wanted to preserve should be in mylar "sleeves".

Now, what kinda plastic is used in picture books?
Will future generations, looking at my pictures see a washed out me?
Will my pretty mug fade away some day?
Better check to see if it's mylar.

PVC has oil mixed into it during its manufacturing to make the PVC soft and flexible since pure PVC is hard and brittle. What you are seeing is the oil leaching out and the paper soaking up this oil like a blotter.

The document would begin to turn varying shades of light brown usually beginning at the edges and working its way inward. The paper can also become very brittle and tends to crumble easily.

<< <i>Why PVC holders are still made and sold within the coin hobby is beyond me.
Agreed. It would be nice if a few of the largest coin supply houses would publicly make a stand and not offer these for sale anymore.

In the end, its all fleeting whispers and dust. Such is the lot of mortal men.
PVC like Exlax just helps things along.
My son just told me the other day he turned in a crack smoker at 6:45am under his french class portable classroom. Then just yesterday he turned in a huffer. The kid was huffing brake cleaner.
Why or why.

Public school? Big city?
Private school? Small town?
Good to know, I'll stay away from PVC.

What is "GULE"?
I never had any GULE sniffers for friends that I know of.
Of course, I never had any Gays for friends either, that I knew of.
