Hi Karen - would love to see some more photos from you - whatever the type of glass, but can't guarantee we'll come up with the answers.

ids for glass without labels or sigs. can vary from difficult to impossible - help comes in the form of other web sites which display glass from a variety of sources to provide the necessary comparisons - books which are essential if you're serious about collecting - and then of course there's us

In the nine or ten years I've been a member on GMB, the available knowledgeable folk here have sadly dwindled enormously - we've had authors of books and some well known dealers in past years, but now some collecting areas lack people to help, entirely.
Don't know where you are, but do also remember museum collections, antiques fairs, galleries etc, can help - and you don't actually have to buy their wares - just look and learn, and don't drop their pieces

Your piece of glass is almost certainly Scandi - but the maker may well remain unknown - it's a good piece - perhaps not so collectible now as it might have been some few years back, but it's useful and provided it has avoided excessive water staining then should be a good item for show.
Struggling to id pieces is a common situation for most of us - you may find that as time passes you concentrate more on one area - it does have the advantage that you do become good at your chosen genre - being a jack of all trades is o.k. but you never perhaps feel that you master any of them.
