The seam that I think I glimpse in the last photo of the first group, Master suggests

The last photo of the first group, and the first two images of the second group, also make me think of Master, but only minimally

Yes, jabo or champion

Gel type ...

Super sparkling ...

Thanks Ron- Yes, veiligglas is the master, without any doubt! It will probably be very difficult, but I hope that in the future some document can emerge that certifies some production of these also in Germany

German slag

some still ..

Anyway, when I find a vire pull I will say veiligglas with reserve of 5/10 % of German

100% safe they were produced in Amsterdam, on this it does not rain, as there was the veiligglas glassworks, and in its disposal, many pull vire were collected

It can be assumed. In a thread about veiligglas, a guy claimed that machinery had been found to produce vire pull in Germany, but there is (so far) no documentation. Maybe yes, maybe not?

These are some of mine, if you wish, I can post again.....

I asked a collector of marbles who lives on the border of Germany and yes, as Ron also says, no document has ever been found that they were also produced in Germany, one can only suppose. The guy I spoke to thought they were also produced in Germany, the most beautiful, densest ones, because he often found them in Germany along with German slag and even German artifacts. Perhaps, it seems, they were produced even before the Second World War

It's the same, but the op is in a different light, very strong...
