I still wanted to try to understand Winnie's header translations better before I posted them since I didn't recognize some of the words. But now I'm feeling pressured to understand faster because it sounds like it might be relevant to the Alley aventurine discussion. Maybe a little.
Unfortunately I can't understand things on a schedule. So this is just a bump for the people who are talking about glass colorants from last century. It sounds like maybe Greiner and/or Muller sold things like that.
For instance, what would glass tubes, glass rods, colors and fusion colors mean to you? Those are mentioned in the Greiner header. It sounds at least possible that some is for making other glass items.
p.s., other items mentioned in the headers are glass marbles, panorama and garden balls, Christmas decorations, eyes, et cetera. Some of the other items sound decorative and some sound more industrial/commercial.
