My obsession includes purchasing any plinths I find at a reasonable cost. That particular one I think is a Davidson cloud glass as its colours appear to me to be briar and topaz. The lamp fits/stands/balances nicely on it. As the bulb is fluorescent and does not give off a lot of heat I was not overly worried; thank-you Bernard for your advise I will keep and eye on it. Yes the flex comes out the side of the lamp and over the rim of the stand. There is normally a lot of clutter of trinket pots and candlesticks surrounding the lamp so a little elevation was in order.
Antiquerose123, beware the addictive qualities of seeing your own glass under black light. I started with a small torch (I would carry in my bag when I went glass shopping) from here http://www.homeofpoi.com/
, then to this bulb and now I feel the need to black light a display cabinet!
