This is a pair of Bohemian small glass vases. The maker is Harrach. The age is circa 1885, when Harrach produced this type of glass.
The glass was difficult to photograph and there are light glares that may appear as streaks of white enamel, however the white enamel is limited to the painted bird scenes on the front and the leafy display on the back.
Each vase rests on three glass ball feet. The height is 4”, the width at the mouth is 2” and the width at the body is 3”.
The glass is called Marmor and is typically found in aquamarine blue; the green is quite rare. I think the glass is cased or layered, with a clear glass on the outside and inside, and the green with black lines sandwiched between the two clear layers. However I might be wrong; this is just my best guess as I am not a glass blower.
On the front is the hand enameled scene of a heron resting on one foot in a pond of water, surrounded by pond foliage. The birds face each other if the vases are lined up correctly. The backside of each vase shows a spray of foliage.
The rim is ground flat and slightly beveled on the inside. The gold trim on the rim is mostly worn away. One vase has a tiny chip or flake on the rim that was covered with gold.
The pontils are smooth and slightly protruding from the bottom. One vase has the number 11 hand enameled in gold over the pontil.
