Without a label, Empoli could certainly be a top contender.
Some confirmation is required before we conclude anything, I reckon.
I just have a very strong memory of being surprised when I saw a pale, slightly green kingfishery blue vase exactly like this and learned it was Polish. It was a long time ago, and I can't remember what it was that identified it, it might well have been a Made in Poland label that surprised me.
I was trying to find out about Polish glass at the time. Very little was known.
But seeing one in that orangey red and in neodynium glass is knocking big holes in my Polish confidence.
