Greetings everyone!  (This is my first post)

I have a torchiere floor lamp that I got from Walmart a few years ago and absolutely love it.  It's the same model as this one:

I'll spare you the story of how it happened, but the top of my globe is now broken and I need to find a replacement.  It doesn't have to be the same model or even functional (I can gookit it), just as long as it fits.  I also don't mind if the replacement globe flares out on the sides, as long as it sits securely in the socket.  Fitting into the decorative plastic top cone would be a plus, but is not essential.  One more important note: it's not shown in the pictures, but there is a metal arm that holds up the top portion of the lamp, so the globe is not structural to the torchiere.

Here are the measurements of the original globe:

-Width of base:  2 and 7/8 inches / 7.3 cm

-Depth of the lamp "socket" that holds it above the bulb: 5/8 inches / 1.5 cm

-Height of globe (including beer bottle-style cap, but not the outer metal cap or decorative cone): 10.5 inches / 26.7 cm

Any ideas?  Is there another, more common model of lava lamp with a globe that would be compatible?

Would a wine bottle work?  It seems to be a fairly common bottle diameter and I've found a couple that might fit, but they would have less capacity than the original and I'm not sure if they're up to the temperature stress.

Thanks!

Shawn
