Hourglass "Bulb"

[Dustin Lorenz]

Anyone know where to get the glass section to make your own hourglass? I know Rockler has one but I am looking for something bigger. I'd like it last at least an hour, and be at least 18" tall x 6" in diameter. I haven't tried any custom glass blowers, however I'm pretty sure that would be my most expensive way to go.

Lee Valley sells them, a few sizes, but I dont think as big as you are looking for.

I've also seen them at my local Woodcraft store... they seemed to carry various sizes, but probably not 18" tall...
