Murano, Kralik, unknown!

InHello all, this is my first post.
I was hoping someone could help me identify this striking orange and black vase. It's very heavy, weighing 2.85kg, it stands 33cm tall and is 28cm at its widest.
I can't see any marks or signatures and using Google lens proved unsuccessful
Many thanks

Way too big and heavy for Kralik. Quite unusual, though not impossible, to find a ground down polished pontil on a Murano piece. Sorry I can't help beyond this.

Just to add to the above, I have come across a Kralik Bambus floor vase on Collector's Weekly so ruling it out on the basis of its size was inaccurate. However I don't think Kralik ever did those ground, polished pontils on their bases, so I would still think them unlikely.

Thank you for taking the time to respond to my request for information. It seems can rule Kralik out! I'll see if anyone else can throw some light on it - Many thanks.
