Bohemian Art Nouveau orange iridescent crackle glass vase

I’m always on the lookout for “sleepers” on eBay, that is, items that are incorrectly attributed. Sometimes they can also be cheap, this one wasn’t particularly cheap, but certainty not expensive either, for what it is.
It was described as MCM carnival glass. I’ll just leave that out there…anyhow, despite a slight resemblance to carnival glass due to being iridescent orange, it isn’t.
The vase measures 20.5 cm tall, 5.2 cm across the cut & polished top rim, & 8.5 cm across the base. Of a simple flared form, it is made from translucent orange glass with a crackle decor & an intense iridescent finish.
Most likely Bohemian origin, circa 1900. I know various makers did crackle decors so not 100% certain who made it. Maybe Kralik?
