not Peloton - that has small threads (often multi coloured) embedded in the surface (iirc)
not threaded either I don't believe.
It could be called 'relief decorated' as a simple description but I think in reality it is :
crackle glass,made again iirc by dipping in cool water?? so it crackles and then blowing out again to enlarge the crackle.
The surface finish iirc may be dependent on whether it is reheated (so the surface crackle is 'soft'), or not which would leave the crackle fairly rough. I think... open to correction from a glassmaker or anyone else.
I am not sure which British maker used this technique - Apsley Pellatt did say in his book he made a form of crackle glass though but that was c.1840s and I think a different type of crackle. Too late to go and look in the book at the moment.
I think it's most likely to be a Bohemian maker (but that's just me).
I think there was a long standing discussion on Loetz using this technique and somewhere there are some larger crackle water jugs with angled handles that iirc were made by Loetz??
Kralik did make crackle glass as well.
Also another maker (cannot remember name for the life of me - maybe S. Reich & Co ?) who made lampshades, also did crackle glass. I put some info on the board somewhere relating to 'crackle glass lampshade' title or similar.
All open to correction
