Czech cased orange spatter glass mini vase

Yesterday I went to the last bi monthly antiques fair of the year, & as always, I made some great finds & had a fun day out. There was a lot of interesting glass on offer, one example of which was this tiny vase.
It is made from cased glass, clear over a greyish - white spatter, with a deep orange interior. For a small unit it has quite a presence & plenty of charm.
It measures 8.1 cm tall, 2.3 across the top rim, & 4.5 cm across the base.
Czech origin, circa 1920s. Looks a little Welzian to me…not 100% sure though…
