A delicious looking piece of glass, TC - and my apologies for not posting sooner (as I have written in another thread here; sad, family circumstances have meant I was away from home).
Not Carnival, as Ivo has already explained. I'll just add a little bit extra which may help for the future. To be classed as Carnival, an item should have the following characteristics: iridised, (press) moulded and with a pattern.
The pattern would be moulded (i.e. formed courtesy of the mould and plunger) though there are a very few exceptions where a design is enamelled or etched. (I stress that these are exceptions, and even when the design is enamelled or etched, there is often a moulded pattern too).
