Identification Help - Manganese, Neodymium, Reproduction, Other
Okay so a couple of things here. I found these all together for $5 at goodwill total. My first thought was neodymium, and I was super stoked. Moving them from inside Goodwill fluorescent lights, to outside, to in my home, I've seen no color change so I'll rule that out.
Now I love vintage glassware first and foremost, and here and there I'm okay with later reproduction as long as I like it ¯\_(ツ)_/¯, and I have a feeling these could be but want some help. Most have a seam, which tells me it's molded. The oil-like-pitcher to the far left has a seam and a pontil. I did check with a 365, they do all have manganese in them. I've read (just today found out) about sun-affected clear glass with manganese pieces that turns light purple. My issue is that the pieces to me feel newer, but then again manganese isn't often used in "newer" glass anymore. When I say newer I personally am referring to post 1980s. Google lens (I know not the most reliable) was telling me the thin glass (2nd over to the left) is Fostoria. It's so thin it almost feels like plastic but it's not.
Out of all of them, the single salt shaker is my favorite. If anyone has any ideas please feel free to share💜
