This is a pair of Bohemian art glass vases. The glassmaker is Rindskopf. The date is circa 1900.
The type of glass is called Pepita by Rindskopf, characterized by a dark red wine burgundy color at the top and going to a green color on the sides and bottom. Other makers call this type of glass rubena (rubina) verde.
The glass is quite light, so it is most likely mold blown.
The iridescence adds color, giving the glass shades of blue, yellow and gold in certain light. I can't tell if the iridescence makes the glass look green, or if the glass is actually green.
Each vase is 9 1/8" high and 3 ¾" wide at the lower bulge.
The glass is paneled on the long neck, slightly tilted, and bulging in so that you can feel the ridges on the inside with your fingertips.
The rim is polished flat.
At the rim, there are a few blemishes from the glassmaking process, causing a crevasse at one rib and some nibbling when the rim was polished.
The bottoms are flat with a slight indentation.
The glass is Pepita, however the shape is unusual for Rindskopf, so do examine all of the photos carefully.
