It does. I evaporated the alcohol tinture down to half with a fan. Added the glycerin and now attempting to decrease further using a fan and heating pad. I have a gas stove so no double boiler
You may find an electric stove top cheap on line or in a bargain store
Coffee mug warmers work well too
If you reduce the tincture all the way down use a little xanthan to bind it to the glycerine, there is also a product called 210S that works better
If you leave some alcohol and mix you can make an oral spray out of it
