I am about to attempt to make my own Alkanet oil. I have read on one of the threads here (in the archives) that you should either steep or boil the root in alcohol, then combine the mixture with some boiled linseed oil and/or tung oil. Is the type of alcohol important? I mean can I hit Wally world for some Rubbing alcohol or should I get some denatured stuff? Maybe I can try some Grey Goose as well?

Thanks in advance!!
