Acetone next time would melt it out.

Braver than I am to put it on the grill. There are a lot of "unknown" materials that will offgas and cause an explosion. Turned out good though. I'm thinking it was some type of shellac/varnish/creosote or something

You're more patient than I am. At that point I would have left it, as I have done with several other bottles already...

Great work!

I will keep that in mind if I get another like this one.

Yea, I warmed up the bottle slowly and that thought that you mentioned entered my mind. I did keep the lid on the grill closed unless I was cleaning.

yea, I am retired and have more time than sense sometimes. But the end result turned out ok.

That’s what I would call dedication to having the most complete St.Louis soda bottle collection that I have every seen.

Thank you for the kind words.

Mineral spirits is a good solvent for many tar-like substances. If that doesn't do the job, acetone - as robbybobby64 suggested - is a potent solvent.
