How does rust happen in a CGC slab? 1 1

[hermanenwang]

Sorry if this topic has been answered before, but I tried searching the forums and cannot find a definitive answer.

I thought that there was an inner layer for a CGC slab that completely encapsulates the comic where air doesn't go in or out, so how would outside humidity affect an CGC slabbed book?

Do you have pictures? 

I wonder if what you are describing is Newtons Ring? 

 

Humidity can effect comics inside a CGC slab, which is why proper storage conditions is important.

CGC cases are not air-tight. You must store all of your comics in proper conditions to prevent rust.

Just to add to all of the great advice given above about storing books in the proper conditions, let me add for the OP and others viewing this page...

CGC cases are not UV Protected.

Ah thanks. Yeah I figured the case doesn't have UV coating, but I thought that the inner plastic envelop sealed the comic. I thought someone on youtube showed throwing a CGC slab in a bucket of water and the comic was fine.. but maybe it was because it wasn't in the bucket very long.

Well, let's just say that not all slabs are created equal.

You're correct that the inner well is heat sealed, but not all slabbed comics have an inner well. And I'd never advise putting a slab in a bucket of water as a test---that could be an expensive mistake.

I'd venture to say that the newer slabs are much sturdier and seem to be more resistant to humidity, but it's still wise to follow all the proper storage conditions...

Yep thanks! Better safe than tears later.

Also, storing in a firebox or safe is not a good idea, especially with regards to encouraging rusty staples.

No, slabs are not airtight. Comics need to breathe or they will stew in their own juices.

Rust can happen:

I'm more than a little concerned that the humidification of books before pressing, might be the cause of some of the rusty staples we've been seeing?
