All you have to do is google "soft glass rod" + price, and you get two hits. I checked one of the hits and at the bottom of the page was a list of glass suppliers.

If I really set my mind toward trying this trick of Prince Rupert, it seems it would be possible.

Ain't the internet just great?

P.S. I saw some stained glass windows from the Middle Ages today in a Richmond Museum. The color just blew me away the way it does every time I see them. And the Tiffany lamps are super-extraordinary. There were these types of Tiffany lamps on display: dragonfly, begonia, peony, wisteria, peacock, autumn leaves, cobweb (my absolute favorite!), and lily pads among others I can't remember.
