Bohemian Art Nouveau green iridescent glass vase - Welz Maze

I picked this up on eBay UK late last year, & it arrived today.
This Art Nouveau vase is made from a single layer of green glass with an intense iridescent finish. It measures 18 cm tall, 5.7 across the top rim, & 6 cm across the base. The vase has a uranium content verified under UV light.
There is a raised labyrinthine pattern, which is what caught my eye inititally - in the second photo it is shown beside a light amber/brownish vase with the same decor, identified as an example of Welz Maze.
Bohemian origin, circa 1900.
