Well first, as Della says, "get well soon". The after effects of general anaesthesia are long-lasting, aren't they (she says, remembering back :cry: )
So, is it Carnival or isn't it? It's not mainstream, Classic Carnival. Strictly that is iridised (press) moulded glass with a pattern. I have put "press" in parenthesis as Carnival may also be blown into a mould. Press moulded is the norm though.
Your decanter is iridised - and indeed has a marigold iridescence. But what I can't see on it is a moulded pattern of any sort. Is there one? That really is the final key.
There's a lot of iridised glass that is borderline Carnival. Purists would say it's not Carnival. But there are others who enjoy a wider outlook and embrace items that are on the fringe.
It's an attractive and elegant piece of glass :lol:
