I just got 5 ounces of cosmetic grade beeswax. This is plenty for me, so if you would liks a free sample (a few grams) and you're willing to send me a stamped self-addressed envelope, send me email at [email protected].
And, while we're on the subject, how might one remove beeswax from the string and nut? The Wikipedia article mentions turpentine as a solvent. To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
