The "Stoddard" Stubby bottles that are pontiled usually have a sand chip pontil. I have more of these bottles than anyone needs because I really like them, and none of them have an iron pontil. (They are all different, too) That one looks like it has iron residue, but it is a bit hard to tell from the photo.
The olive green color is definitely more scarce than amber. I'd have to see some backlit photos to show the color better before I could say what I would pay for it.......the amber ones go for anywhere from $65-$115.......
I'm not sure about Stoddard having IP's or not but I think the "Stoddard Stubbies" were also blown at several New England glassworks.. I think kungfufighter & earlyglass could answer this more accurately..
Yes, iron pontils were used... example, the Kimballs Jaundice Bitters and Smiths Green Mountain Renovator.
Many medicines, utilities, ales and stubbies had iron pontils, much of which was done at the Weeks & Gilson works.
I always say "Stoddard" stubby because that is how they are commonly known, but put Stoddard in quotes as they definitely come from any of a number of New England glasshouses.....
Good info Mike. Those are good examples I can't believe I forgot about those two? Have you ever dug at the glasshouse site?
I use the term also Cindy. I just try to point out that all crude,amber & olive glass is not Stoddard..If you look at ebay it seems that every amber utility,master ink,demijohn,etc. is Stoddard.
