This is a Bohemian art glass vase. One glass expert told me the maker is Loetz. Until somebody insists otherwise, I will say the glass is Loetz. The date is circa 1900.
The vase is small at 5 5/8” high and 3” wide at the belly.
The inner glass is black. 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; it is the same glass as shown in the book, and only the shape of the glass is slightly different. 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 book references I cited should be enough to confirm for you that this vase was produced by Loetz, circa 1900.
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.
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.
