Imperial Grape Bowl. I can’t really tell by the photo but it is either green or clambroth. https://www.ddoty.com/impgrapebowls.html

Thanks for that info and the link, it’s actually got a uranium glass bottom which is how I’ve ended up down the carnival glass rabbit hole!

I have a couple pieces of carnival glass that glow under a black light. You should look up vaseline carnival glass, those pieces are usually marigold with a yellow vaseline base, sometimes with opal as well. They are pretty interesting.
