lowball Posted March 30, 2023 Share Posted March 30, 2023 Are there any issues with moisture and CGC slabs? Seems that something sealed like that could have humidity issues. Are the slabs air tight? Curious how CGC handles this. Link to comment Share on other sites More sharing options...
ExNihilo Posted March 31, 2023 Share Posted March 31, 2023 Slabs themselves are not airtight, but I believe the inner well is basically a mylar type bag that is heat sealed on all edges. That is (likely) airtight. That said, each collector should house their books in a climate controlled setting that is comfortable for both themselves and their books.

theCapraAegagrus Posted March 31, 2023 Share Posted March 31, 2023 Humidity should always be controlled. Link to comment Share on other sites More sharing options...
lowball Posted March 31, 2023 Author Share Posted March 31, 2023 Thanks. I'm actually thinking about humidity in the books, inside of the sealed part of the case. Has that been known to cause any issues (regardless of where it is stored?) I've had air tight boxes and safes have extremely high humidity inside when the humidity outside of them was very low.

marvelmaniac Posted March 31, 2023 Share Posted March 31, 2023 If the books are being stored in your home that is heated and air conditioned there should not be any issues with excess humidity, I only have two slabbed books and have never encountered any moisture issues inside the case or with any of my books. If you are that concerned about humidity use a de-humidifier in the room or place a Desiccant with the books if they are in a safety deposit box or safe, just remember, for proper storage you want temps between 68-72 degrees and humidity at 40-50%, if the humidity is too low the pages may become dry and brittle. This is from the American Library Association and the Library Of Congress. https://www.ala.org/alcts/sites/ala.org.alcts/files/content/_MeltzerBkmk16.pdf https://www.loc.gov/preservation/care/comics.html Link to comment Share on other sites More sharing options...
MattTheDuck Posted March 31, 2023 Share Posted March 31, 2023 The slabbing process and materials have changed at least a little over time. We now have books that are, what, 20 years in a slab? So far, we haven't heard of any widespread problems with moisture inside the slabs or the inner well, assuming they're being stored as noted above.

rumrunner71 Posted April 2, 2023 Share Posted April 2, 2023 (edited) I seem to recall a thread or two that were about storing in safes (and why not to.) Have you searched that specifically? There might be some discussions with good advice. Edited April 2, 2023 by rumrunner71 Link to comment Share on other sites More sharing options...
