Dirk, As I wrote earlier, I have seen this patina on old ghost town bottles that have been through a fire. There IS some connection. Perhaps the common ground between our comments is that wood ash is strongly alkaline. I remember my grandma leaching ashes to get lye to make soap. Perhaps the accelerated chemical reactions produced by heat combined with the alkaline ash is the key--- Whatever the case, there is an empirical connection with fire.
