Hi Christine. Thanks for letting us know and yes, I have checked the vase under UV light and it certainly looks uranium. I had already checked some of the threads prior to posting the most recent two and to be honest I am still not clear as to the originator. The two that I had posted are different, especially around the base area and lobes around the vase. I have even looked through various books and I still unable to match this up. I am currently waiting for more info. to come through regarding threads and the recent post by TheGlassDept. The problem is that there are so much variations of this type of vase that does require the eye of an expert and I can assure you, I am not. Thanks all the same for your contributed effort! :thup:
