This is a Bohemian art glass vase. The glassmaker is Loetz. The date is circa 1898.
The vase is small at 5 5/8” high and 3” wide at the belly.
The inner glass is ruby red. The glass looks black. However one glass collector told me to shine a line through the bottom of the vase and if the glass looks red, it is ruby or rubin. The glass is red with the light shining through it. Over the black is a vivid blue, what I call a metallic blue, and this allows a pattern of color to come through. Most similar to this vase is one in the book “Collectible Bohemian Glass 1880 – 1940” by Robert & Deborah Truitt, on page 85, number 2. You can see glass of similar colors in the book “Loetz Bohemian Glass 1880 – 1940” by Hatje Cantz, which is an excellent book and worthy of belonging in anyone’s reference library of art glass if you are willing to pay the high price to buy it.
The decor is called Papillon.
The glass has an iridescence which adds some purple, more towards the bottom. There are some whitish streaks that don’t show in the photos and which appear to be part of the glass process.
If you look closely at the bottom side, there is a layer of clear glass showing, however this is the only place it is obvious.
The rim is polished smooth. The outside of the rim has a wider bevel; the inside of the rim has a smaller bevel. Remember to look for this specific beveling if you are examining unsigned art glass and you think it might be Loetz.
The bottom shows a lot of wear. It is indented and continues the pattern of threads.
There are a few tiny pinprick nicks in the inner rim edge. The glass shows a little bit of handling wear. The bottom shows the most wear.
This glass is amazingly high end and quite beautiful.
