Gooseneck decanter Czecho slovakia

Twelve days ago, we purchased this liquor set for 20 USD. It was into a shop not very exposed. I got attracted with the marvelous pearled iridescence and the bluish green color of the glass. One of the four glasses has a chip on the top. My son Ricardo, the special boy with me on the picture, put it under the uv light and it glows…. So it is uranium glass (first picture, the flash does not let me to catch the full fluorescence). I had no other uranium glass so bluish. The glass is optic and has no pontil. I found one very similar on the web https://www.ebay.com/itm/Czech-1920s-Art-Glass-Gooseneck-Iridescent-decanter-and-plate-REDUCED-/381516919181 that has the mark of the last picture, our has no mark on the bottom.
The pear like shape could be indicative of intended to use with pear aquavit.
Thanks for any comment.
