This is an English art glass tazza, made by John Walsh Walsh. The date is circa 1900.
An almost identical tazza is featured in the book "Victorian Decorative Glass British Designs 1850 – 1914" by Mervyn Gulliver on page 198. It is the first page on Chapter Three titled "Designs for Food Containers." The tazza featured on page 198 is smaller than the one I have listed here for sale.
This tazza is 5" high and the top is 6 ¾" by 5".
How the author describes the tazza in the book applies to this tazza too. The author wrote: "A small tazza manufactured c 1900. The rim is finished with a very shallow twelve-way crimp. The stylized leaf shaped dish is formed in clear glass from a mold with twelve equally spaced out bands of small, closely spaced, shallow projecting ribs. The dish is supported on a green glass, stylized rustic tree trunk and base formed with six matching tree-root feet. The base has a snapped off pontil mark. All surfaces of the tazza have an iridescent finish. The color and texture of the iridescent finish, and more importantly the rib pattern, suggests that the tazza was probably manufactured by John Walsh Walsh. "
There are no chips, nicks or cracks. Any roughness or sharpness to the glass on the stem was manufactured that way, so as to emulate a tree trunk. In one photo, with red arrows, I point to two small protrusions that are not chips, but merely where the green glass ends between the tree root feet, a choice made by the glass maker so that the tree root feet remained distinct, and not joined together by tendrils of green glass.
