This is a 20th century Bohemian Moser glass vase, circa 1910 to 1925.
The vase is 10" high and 4 ¾" wide.
There are four applied raspberry prunts with a central dome in the same color of blue glass. Going down from the prunts are large blue glass drops. The body of the vase curves in at a straight neck, and tapers down to a round foot. There is a band of white enamel beading around the neck and foot.
The hand painted enamel designs are extremely beautiful, and obviously painted by a professional artisan. On the front of the vase there is a white and yellow rose, just beginning to unfurl its petals. There are green and white leaves on long stems. On the top right is a huge colorful butterfly, perched on top of a leafy stem. The butterfly is enameled in yellow, brown, purple, lavender, gray, black and pink. There are some grassy long leaves. Towards the bottom of the vase are leaves and branches painted in brown and yellow-orange enamel. There are some leaves in gold and black.
On the back of the vase are two butterflies in flight, painted in vivid detail.
There is a similar blue glass vase, featured in the book "Moser – Artistry in Glass 1857 – 1938" by Gary Baldwin & Lee Carno, Plate 158 on page 91. The citation for the blue vase in the book is Moser, circa 1920. The similarities are the shape, the same white beading around the neck and foot, and an enameled rose on the front with the petals unfurling along with enameled insects. The rim is more rounded than I am used to seeing in Moser glass, however there is a slight beveling on both sides (chamfered.) What is different are the applied prunts and drops.
The glass in the Moser book is described as being "copper-blue."
You can also view two similar Moser blue vases showing the same enameled roses in the book "Moser Artistic Glass Edition Two" by Gary D. Baldwin, page 129, Plate 139.
The gold trim around the rim and edge of the foot is mostly worn away. The large glass decorative drops show fissures and bubbles within the glass, which has something to do with the process of applying glass to glass. One prunt feels a bit rough to the touch. There are a few air bubbles. There is a little bit of residue on the glass inside the vase. There are some lines contained within the glass, that can be viewed with a magnifying glass, which is part of the glass structure. There is a flea bite nick on the inside rim. There are no chips or cracks.
The pontil is difficult to see. It is polished smooth and is only slightly concave, almost level with the rest of the bottom of the foot.
