This is a German WMF (Württembergische Metallwarenfabrik) vase in Myra glass in the shape of a ladies spittoon. The date is circa 1930.
The shape is 7" high and 7" wide, with a round belly and a thick neck that flares into a wide rim at the same width of the belly. The prior estate owner of the piece was a wine gourmand and the vase was on display at his wine tastings to showcase as a ladies spittoon, too fragile for that use, but used for display at the wine tasting functions. The wine would be tasted in the mouth and then spit out, but into a more durable porcelain spittoon.
WMF applied chemicals to the glass to create the iridescence. What is unusual about this piece is that the neck and mouth are yellow-gold, but the belly is silvery blue. The chemical application does not go all the way down on the outside or inside. The chemical application also alters the shading of the color of the glass, and in some light it appears quite yellow, and in other lights it appears to be a dark red. A last interesting feature is the glass itself; there are horizontal wavy lines in the glass, almost like there are different layers of glass, but stacked from bottom to top, not from inside to outside. You have to look at the photos carefully to see what I am saying, and zoom in where you can. I am not a glassmaker so I can only describe the vase the best as I can.
The white spots are light glares in the photos. This vase is very refractive and I tried my best to take photos of the glass in different lights so as to avoid having my face and camera be reflected in the glass.
The pontil is round and snapped off, leaving a line in the glass that goes all of the way through. I don't know if this means the vase is a one-off or if this is how Myra glass is made. There are no chips or nicks or cracks. There are some light scratches in the chemical layers and I assume some of the chemical application has worn away due to age and handling.
The glass is very thin and fragile, and it totally amazes me that this piece has survived to be owned temporarily by me.
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.
