Is it ok to use a small coffee warmer that says it will keep a cup of coffee at 120f on high setting to evap before doing my freeze precip?

No.

Never evaporate solvent on an electric burner.
It's just good advice.
If someone is capable of evaporating solvent with heat, they don't need to ask the question.

I spaced. You're right. Electricity = possible spark = possibly ignite. Forget I said anything

Best to take your time than to take any risks b

Well how about the temp range...any harm to the Spice?

Its not the temperature, it's the fact that sparks could be created that will ignite your solvent-

Yah I wont be useing it again,just wanna make sure that the lil bit that I had evaped before the precip is good to go.

It will be fine. Enjoy and let us know if you have any further questions.
