I have been using high proof vodka to make oil extractions. Normally I reduce in a double boiler then leave out for final evaporation till I have oil. Time was short and I was only able to reduce half way so I covered and put in the fridge. Later I noticed black solids had formed so I strained and got some "solid oil" a black goo that stayed together but when put on a wax paper plate spread like oil... it is very strong.
PS
I am also making more "purple oil" I will post here when I get going
