Having used one of these for years, both the DFV-1 and the newer DF-2,
trust me when I say DO NOT put shellacs in them it will absolutely
destroy them, These Furutech work brilliantly on 12 inch vinyl lp's
only and nothing but. (You also can not use them on lp's weighing less
than 110 grams.

Yes. Most common method is to put the record in between 2 sheets of
flat glass, put the "sandwich" in direct sunlight until the shellac
softens enough to unwarp the disc, remove sandwich from sunlight and
let cool 2 or 3 hours. Voila, a flat disc.
There are exceptions to this method. It doesn't work on Columbia
laminates or "acetate" (lacquer) discs, either.
Ovens have been used, as opposed to sunlight, but not your home oven.
And not a microwave.
The softening temp usually cited is 125 degrees Fahrenheit and most
ovens will not go that low and have any temperature control or
I'm sure others on list will chime in about all this.
