# Drying ethanol

## Recommended Posts

Meth/ethanol spirts. distill it to remove that purple colour.

Then most of this will sink to the bottom and turn more blue from white.

Also some of the denaturing additives (grubbles....) will turn brown'ish.

Still again and its should be done, add a little more copper sulphate and it should just sink and not change the colour of the liquid.

collect you copper sulphate and dry for another day.
