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...

This one, for example, appears to be similar to your first one and seems to belong to the exotic, to the patch but not for sure, it has small features

The fact is that there are many color combinations, (perhaps still unknown) that leave perplexity and cause for debate. The only way is to post and hear various opinions to have more certainty

Fancy = colored transparent base, generally dark amber or green, with 2 or three colors with possible traces of white Exotic = neutral transparent base, or light amber transparent base with 2 or three colors including white The difference in my opinion is that the fancy have a more colorful transparent base than the exotic ones

Well I think there are some very obvious, safe exotic and fancy,conquerors, others may be similar (by color combination) without having a total certainty

I think the ones I've highlighted fall into this category of exotic or fancy, but it would be better to have individual photos
