Interesting Red, Thats a lot more then I've been able to find out. All I could confirm about iron pontils it that when the bottle cooled, it fell off, sometimes they would get stuck if pushed to deep in the glass and the had to be forced off, but other wise they just fell off! I guess the workers had to work quickly to finish the lip before it cooled to much and there were a few mishaps now and then...
I've never hear of lead being used before but it make perfect sense to me for the white graphite pontils as they are called. In fact I had thought to myself before that they really looked like a lead deposit! I think its time someone takes samples of different pontils and tests them for their content when it comes to these marks...
Doug, I dont know about the solid bottles but the sample Vernon bottles have "PAT'D - MARCH 25 - 1892" on the base, no makers mark.
