if I may reply to Pamela first ........
Sorry, my German is inadequate to understand fully your extract from the 'pressglas-korrespondenz' - however, do I understand you correctly that whilst Josef Riedel discovered the process of adding Uranium to glass, it was in fact Franz Anton who gave us the names Annagrun and Annagelb - in reference to his daughters. The reason for asking this is because, as was implied earlier in this thread, one of my glass dictionaries suggests that 'Annagrun' was named after Josef's wife....."as was also Annagelb".......and my only other dictionary suggests also that.........."Annagrun and Annagelb- introduced by Josef Riedel's Dolny Polubny factory, and named after his wife, Anna Maria". However, it seems that in the light of what you say, these books are probably innacurate.

Books such as dictionaries suffer probably more than most from inaccuracies (too many details to be checked, so SOME editors go for the quick fix, and simply copy from another dictionary) - Samuel Johnson excepted of course

However, as Lustrousstone now seems to indicating - my pieces are neither

- unfortunately, I don't have time to reply to Lustrousstone this evening, so will have to be tomorrow.
thanks again Pamela.
