I would put it on a ceramic plate and let it evaporate and scrape the remnants with a razor blade.
Yes all that in one sometimes

Fan blowing over the top won't hurt it none
I would stick the jar in the freezer for a couple days and then filter it through a coffee filter, before evaporating it away in a Pyrex pie plate or casserole dish.
The "Winterizing" step removes the inert plant waxes.
Isopropyl is rated by the FDA as a Class 3 solvent, so the allowable residual solvent is as follows:
Solvents in Class 3 (Table 3) may be regarded as less toxic and of lower risk to human health. Class 3 includes no solvent known as a human health hazard at levels normally accepted in pharmaceuticals. However, there are no long-term toxicity or carcinogenicity studies for many of the solvents in Class 3. Available data indicate that they are less toxic in acute or short-term studies and negative in genotoxicity studies. It is considered that amounts of these residual solvents of 50 mg per day or less (corresponding to 5,000 ppm or 0.5 percent under Option 1) would be acceptable without justification. Higher amounts may also be acceptable provided they are realistic in relation to manufacturing capability and good manufacturing practice (GMP).

I did this.
The green slime that was left in the bottom of the mason jars was quite yucky.
Hey Grey Wolf, do you just leave yours to evaporate naturally? Or do you use heat?
I see people putting the iso wash straight in a crockpot, but I've always been a bit scared of burning the oil so I put it in a pyrex bowl floating on hot water in the crockpot.
It will speed it up quite a bit actually, but increases the amount of dust and hair that comes in contact with the surface, as well as atmospheric humidity.
If you stretch a towel across the dish and blow across the towel, it will speed up evaporation and when you are down to a beige liquid, you can place the dish in the fridge to harden the resin and pour or wick off much of the 5% plus pickup water that is left after most of the alcohol is gone.
You can evaporate away the balance in a warm oven and the fumes given off will be significantly below Lower Explosive Limits.
Can’t remember last time I had a night like that dwelling on undone chores. You may need to take a morning smoke now and then…
I actually use a vacuum chamber or oven, but have boiled off the alcohol by setting it in a 250F hot vegetable oil bath and monitored the concentrate temperature closely.
The solution can't reach 250F until it has boiled off every constituent with a boiling point below 250F, so you pull it out when you reach 174F at sea level.
We set our own goals and decide how we feel about things.Can’t remember last time I had a night like that dwelling on undone chores. You may need to take a morning smoke now and then…
Consider the following dichotomy after you bring your wife home a dozen red roses.
Does she respond with, "How sweet, he loves me" and feel warm and fuzzy or "What has that sneaky son of bitch been up to now" and feel disappointment and anger?
I guess that would depend on if he’s a sweet romantic guy or a snake in the grass. I usually try to be optimistic in most situations but if it looks like a duck…

A crockpot works quite nicely also.

Then you have nothing to worry about
I've pressed Rosin and shared some fine Rosin by others! Especially when pressed from dry sieve instead of leaf.
There is high terpene retention producing good flavor and effect.
The biggest advantage solvent extraction offers is that it produces a quality extract at a substantially higher yield and thus lower price.
Beating the plant material to get substantially higher than 50% yield starts to green out the kief with plant debris, where nonpolar low boiling point solvents remove most of it without extracting polar chlorophyll.
One way to offset that is to process the dry sieved plant material with a low boiling point non-polar solvent to glean the balance.
I like the hot oil in a Cuisinart fondu pot, so that I have precise temperature control when subsequently decarboxylating.
Unlike water, the oil doesn't evaporate away and the Cuisinart has more precise temperature controls.

I worry about failure every single day.
Not much going on. Mom is coming over and making meatloaf. Hanging out.
