[78-L] Can vinyl be unwarped?

[Rodger Holtin]

Vinyl stretches, so the usual warps won't fix at all, sad to say, because you can't shrink the stretched plastic back into shape, so forget the heavy glass method for them.
 
For shellac 78's you can get plate glass from most any glass shop, sometimes hardware stores, but mostly they will stock the light stuff for household windows and that's too light, too thin.

I realize this is not for a 78 rpm disc (it's a Kim Clement gospel LP 
from 1983) however the record is badly dished so that I can't play it 
well on the outer track of the first side. My question is can a vinyl 
LP be safely returned to flatness in a household kitchen oven between 
2 sheets of glass? If so then how can it be done safely? What 
temperature should I use? Where would I get the glass to put the 
record between? Or is there a better way to unwarp a record? I'm open 
to any ideas.....
