I doubt that a colonial gunmaker would use beeswax for sooting parts. Candles were reserved fro use as a light source, especially in the house, because of the relatively low level of smoke. I suspect that hog fat was melted into an earthenware bowl containing a wick, much like the smudge pots of 50 years ago that were used along construction sites. I use a wick in a small bowl with lamp oil. It produces a much sootier flame than beeswax, is much cheaper and is easy to snuff-out.
