Won't the graded card slabs melt below 350?

I wonder would happen to the card itself at 350 for an hour. Would it discolor? Perhaps swap in a beater card to see

Rough numbers:

cardboard will start to burn around 250 F, amd I'm betting it shows heat damage (singed) even lower.
plastic will melt somewhere between 300 and 450 depending on the type.


Kiinda different, but heres a SLABBED COIN that got melted: http://www.cointalk.com/t209641/

Be careful that you have a fan or open window--there could be an awful smell.

Not so sure it's wise to put plastic in an oven. Burning plastic will produce at least 600 times more smoke than wood, and it is much more toxic. Also there is always danger of a fire. Dave. ps it can also produce toxic fumes BEFORE it actually ignites. Bottom line....Don't do it!
