Evidently you fellows need a refresher in physics 101.
Heat is the total amount of kinetic energy due to molecular motion in a body of matter.
"Heat" doesn't have to be HOT. Does not have to be firecrackers or boiling water. A temp higher than absolute zero is heat!
Therefore, put simply the "normal" degradation of matter can be speeded up after changing the ph of the substance. Soaking a card in water changes the cards ph...making it susceptable (sp)to rapid degradation.
I'm not a teacher...look it up...ask a professional paper conservator..not some guy who does it in their basement.
As an aside, I have heard the best substance for erasing graphite is a balled up piece of white bread. I haven't tried it yet but I saw a video and it looked like it worked very well without the abrasion that takes place with art erasers.
Cheers.
