It really depends how much you mean to heat it.
I know someone who, in his early extraction days, tried to evaporate the naphta with a boiling hot water bath (outside on an electric plate), thinking "Hell, simmered the mimosa with water and vinegar, so why not simmer up that naphta to speed things up?".
Even thought that sweet DMT smell rising from the pots was a sure sign of a big yield coming!

Of course, in the end, not much at all to scrape up!
In fact, air movement is your best friend for evaporating faster.
And +1 for freeze precipitation!
it's about making life a neverending experience of wonderfulness!
