alcohol evaporation

Alcohol boils at about 175 F.
Water boils at 212 F.
So a container of tincture sitting in a boiling water bath will get the alcohol boiled off.
Make sure to use plenty of ventilation, and avoid flames and sparks.
Better yet, if you will be making tincture frequently, get a still that can reclaim alcohol:

I own one of these (from a different source), and it's a Green Oil Machine clone.

 

I actually don't bother to use a water bath to boil off the last bit of alcohol.
My stove has covered burners and an exhaust fan, so I put tincture directly onto a stove burner with the vent fan on. And a nearby living room ceiling fan.
Alcohol fumes won't explode at the concentrations that happen with good ventilation.

 

Are you saying that you heat your tincture to 212°F?

A water distiller off eBay , around $95 , just add alcohol press on and the alcohols come out the spout , which can be reused , ideal for rso when using isopropyl , get at least 3-4 uses from 1 lot of ISO

 

I first reduce tincture using a Green Oil Machine clone, which is a still.

The concentrated tincture starts to boil at about 175 F on a stove top, continues boiling until around 212 F, then a spurt of water steam happens to get rid of the residual water.
At about 230 F, only FECO remains, which can be diluted with oil and lecithin to any concentration.

Sparks, flames, pockets of concentrated fumes, or lack of ventilation make this risky, but the alcohol fumes need to be about 3% of the total air volume before they will explode. I doubt I go above 0.01% in my kitchen, but lack of ventilation can create zones of higher fume concentration.

 

Or use no heat at all and just moving air.

this is the still I use and u can safely use it inside , there is a spout and the alcohol drips into a vessel seperate from the still so no chance of igniting

 

Edit

 

Tincture goes inside, and 190 proof ethanol comes out, leaving the reduced tincture inside the device.
It's a pain pouring out a small amount of viscous fluid from a 1 gallon device, and getting all the medicine.
This was sold as the Green Oil Machine,

but now there are clones everywhere.

It's just that simple and not. LOL Either your trying to clean the tar out of your distiller or you add water to the tincture so you have some liquid to hold the RSO tars and oils in suspension to pour out of your distilling device.

This is the method I choose as getting the tar off the walls of the still was a pain and it also overcooked the RSO further then I like.
What you see under the fan in my photo is mostly water left after I distilled off 98% of the 190 proof.
My still has a temp gauge and I can tell when the temp climbs up towards 200F it's down to just water and when the output goes cloudy I'm done.

Best of luck to you , I just find this distiller very simple to regain most of the pure alcohol used , you just add alcohol/oil mix and reduce , it's just a press of a button , and when it's got most of the alcohol out , make sure to take the lid off and check your remaining rso so it doesn't burn , also be careful taking the lid off as it's very hot
