Glass / Glue as a manufacturing process on old glass?
« Last post by Lapimano on Today at 09:56:13 AM »Hi, I just recently purchased an item online. On the pictures, and in reality after receiving it the style of the design also looked high quality, hand crafted, and just like the authentical ones, but it was in particularly good condition, barely any scratch to the gilding, and what stood out the most: there was a separate pontil mark not just on the bottom of the foot, but on the inner side of the "bowl" (this is a drinking glass), or the upper part of the glass.
After closer inspection, I noticed a slight variation in color between the material which is connecting the stem and the bowl. I was curious, and with a pointy iron I scratched the surface of this material, and it was something softer than glass. It was some kind of glue, whether it was epoxy based, or some other glue I dont know. I dont think this is a repair, as there is no other indication that the glass was dropped at some point, it looks more like part of the intended manufacturing process to connect the bowl and the stem.
My question is could it be an authentical piece from the late 19s or early 20 century up to 1930 as the style suggests, or more like a modern replica?
Also sorry for the lack of pictures, it is hard to upload here as there is an editing process for each picture to fit into the recommended sizes, so I decided to skip on this one, but if you think the above description of the problem is not enough, I can post some, but I hope the glue part could identify this on its own. I would also like to highlight that otherwise the glass looks authentic, it is/could be a high quality replica, not necessarily of bad intent.
