Interesting info, and I appreciated the inserted piece of footage depicting the cutting action.

Very interesting videos. You should post some more, maybe of your collection in situ ?

Interesting .. I wonder why they don't just cut the final bit. Why pull it off? Nothing lude intended by that last bit. 🙃

I have a question -could you date this? The pontil is rough on the bottom. It's very heavy a little over a pound and has the purple hue although it's clear. Any ideas? Any comments or suggestions would be helpful. I was told by someone that it was a condiment jar. Wouldn't there be some kind of Lip on top for a lid?

On non-stemware rough pontils continued to be used well into the Victorian era, so you see them on jugs and so on for the mid to late 1800s even though rough pontils are not seen on drinking glasses from this era. The purple hue is probably an indication the glass contained manganese which was used as a de-colourising agent, but which causes a purple colour on exposure to UV light. They generally stopped using manganese in glass in about the Edwardian period from what I remember. You'd have to post a video or photo for me to tell you what the item might have been used for.

I'm an old person. How do I go about sending you some info? Do I turn pics into a link and then paste that here? Or can I email you? Sorry , I just don't know much about tech stuff.
