>>5778375>Quality of paper affects yellowing more than exposure to air. Cheap paperbacks will fully yellow under the same conditions where high quality hardcovers will remain white.NOPE.
If you place a cheap paperback against the back of the bookcase and stick something ontop, or minimize the gap ontop, the cheapo paperbacks won't yellow as fast.
Its all about oxidization. Same shit happens with plastic, but to a far longer degree.
>At the end of the day quality of materials will determine how fast something degrades but the environment surrounding it can accelerate the processI think this is a no-duh, but basically all plastics are unknown factors. How many Figmas and Revoltechs were made from that cheapo shit plastics that had rapid degrading issues? You think all those toys from the 80s and 90s had their issues pop up in months or even a few years?
It's ALWAYS an unknown until years and years down the line. You're just too short sighted and very anecdotal.
BTW, some anecdotal experience here, but just to show how inconsistant the plastic is. I have an ML Iron Man by Toy Biz whose metallic paint got discolored just by being in contact with other figures. In the same box, Omega Red's and Colossus' metallic paint is still like new.
Just shows how plastics and paints are always changing even within the same line and you'll never know what's safe or not until years from now.
