Deep ruby colour and stands 6" - 155mm tall with three mould seams and opaque at the very edge of rim, presumably where it was re-heated.
Could be a celery, but not sure, maybe just ornamental goblet. Good deep ruby is uncommon - very little real red material is showing on Pamela's site, and there is no mention in Cottle and Murray, with just a passing reference to 'Rubine' in Lattimore and Slack.
Raymond Notley comments that red pressed glass was technically viable only from the 1920's (he warns against buying 'Victorian' pressed red glass - however old fashioned looking, it won't be C19, he says) - how he resolves this statement with the known fact that Sowerby introduced 'Rubine' in 1882, he doesn't say. I have no knowledge of production of ruby coloured glass from the States, and this piece may well be from there or the Continent.
Foot rim is smooth/shiny, and reminds me of the Lord/Jacobean Czech pieces, but from wherever it's an attractive piece - perhaps it's a large rummer and I should fill with a blonde extract of grape
Would welcome anyone's thoughts, and thanks for looking
