No problem at all. If your item glows under UV light it would mean that it contained uranium which, if I am correct, is no longer produced. This would mean that you might better know that it was not made in recent years. However, without the better knowledge of some of my fellow members, I cannot say for sure whether some factories are still producing uranium glass. I seem to remember owning a 1960's Riihimaki vase that glowed under UV but the style of yours looks almost art nouveau so, if it did glow, it would suggest that it might actually be art nouveau and that period would narrow down the possible factories.
