This is an English yellow cased art glass vase. The date is the last part of the 19th century, circa 1880 to 1900.
The vase is about 10 3/8” high and about 5” wide at the body.
The glass is a lemon yellow over a solid white glass (two layers of glass.) The yellow shades lighter from the top to the bottom, and at the very bottom the color is quite pale.
The shape is a round bulb at the bottom with a long stick neck.
The front of the vase is hand enameled with two birds perched on tree branches. There is a bird on the body and another bird on the long neck. The birds are enameled in shades of brown and black. The tree branches are white and yellow with touches of gold. There are blue flowers with white middles. When a seller is describing enameling on glass, it means the enameled paint is raised, and you can see it and feel it. At the base of the neck there are two lines surrounding raised white dots.
The bottom of the vase is ground smooth. There is a slight circular indentation in the middle, showing an indication of a prior pontil. The rim of the mouth is polished flat and there is no beveling or chamfering.
There are no chips or nicks. There are two faint pale lines in the glass emanating from the top edge. I show this area in the last photo, but I don’t think you will be able to see anything. I can’t feel anything, and I believe the lines to be between the two layers of glass. Nothing shows on the white glass on the interior of the vase. The rim of the mouth has one small pinkish mark on the glass. The bottom of the glass shows age wear and slight scratches.
