This is a French art glass spittoon dating to the 19th century, circa 1870.
The glass is two layers of opaline. The interior layer is pink and the exterior layer is white.
The spittoon is 5” high and 9” wide at the top.
The rim is round and rolls under.
The glass is transparent. In the last photo I show my hand through the glass. The glass is light and delicate, not heavy at all.
The pontil is round, indented, and polished smooth.
There are two areas of what I believe are ash flecks from the kiln on the outside of the cuspidor or spittoon, the first on the neck and the second on the bottom, and I point to both places with red arrows; the first area is observable in quite a few photos. In looking down at the top of the spittoon, there are two small dark areas where ash is embedded within the glass.
There are no chips, nicks or cracks.
I live in the heart of the Oregon wine country in the Pacific Northwest. I sometimes acquire antique porcelain and art glass spittoons for sale in my shop, acquired from estates, not because people are spitting tobacco into them, or collecting them, but because a spittoon is used in wineries and the homes of wine connoisseurs. The wine is tasted by savoring in the mouth to detect the subtle nuances, and perhaps swished around in the mouth, and then spit out into a spittoon. This means the estate is generally connected to a thriving winery or is the home of a wine connoisseur. The buyers of spittoons today use a spittoon in the same way, however some buyers use the spittoons for display or as a vase.
