This bowl was hand blown by me in my glass blowing studio. It is very unusual in that its sides have two walls separated by an air space. It has a small hole in the bottom where my blow pipe was attached. That area is ground smooth and polished (as you can see in the third photo). That is also where I have signed it.

It is made of a special glass called "calcedonio." The only colorant in it is silver (yes, the same metal that fine jewelry is made of). I describe the process on my Shop Policies page.

Items made of calcedonio glass display lots of fine detail, and each item is unique.

This unusual bowl is about 7 inches across. [My stock # is BW-11.]
