Heating bestine/iso/acetone/ any highly flammable NP solvent to aid evaporation is just a bad idea imho. Granted if you use a hot water bath, outside, away from heat elements (electric/gas/ceramic/whatever), it can be done safely.
But a heptane/butane/hexane quick wash, evaped safely, then redissolved in minimal etoh, or dry cleanly evaping acetone/iso is the best way imho. After the alcohol evaps, warm the dish up in the oven (AFTER THE ALCOHOL HAS EVAPED!!!!!) @ 150 for a few minutes to warm the glass then scrape up and work it around a bit (scraping, spreading, repeat) to evap the last traces of alcohol and minute traces of your NP assuming theres any there.
Alternatively vac purge the heptane/hexane/butane oil, or redissolve it in iso/etoh/acetone after evaping your initial resin, evap and then vac purge it. Its easy if you have a vac flask, some long tweezers/surgey clamps and a glass vial. Just cap the top of the flask with a piece of heavy duty glass and a rubber seal and purge to 20in hg. You'll see the bubbles, and it makes a very fine product imho. Just use a proper vac flask, a cap that won't fail due to the vac pressure at the top of the flask (heavy glass, or better yet thickish metal.

In a society in which nearly everybody is dominated by somebody else's mind or by a disembodied mind, it becomes increasingly difficult to learn the truth about the activities of governments and corporations, about the quality or value of products, or about the health of one's own place and economy.
In such a society, also, our private economies will depend less upon the private ownership of real, usable property, and more upon property that is institutional and abstract, beyond individual control, such as money, insurance policies, certificates of deposit, stocks, etc. And as our private economies become more abstract, the mutual, free helps and pleasures of family and community life will be supplanted by a kind of displaced citizenship and by commerce with impersonal and self-interested suppliers...
The great enemy of freedom is the alignment of political power with wealth. This alignment destroys the commonwealth - that is, the natural wealth of localities and the local economies of household, neighborhood, and community - and so destroys democracy, of which the commonwealth is the foundation and practical means.” - Wendell Berry
