Hi Blorengia and welcome to the GMB! That's an interesting way to have found us - I am the member who originally posted the query about my Blackwater mouse spill vase - and I'm afraid I have not been able to find out anything at all about Blackwater glass, although I have tried my darndest.

Is your vase exactly the same as mine? (If different, a photo would be good if you could!)
I too have seen maybe one other (now 2) Blackwater items on Ebay - so maybe they are fairly rare,I don't know.
You've had yours a long time though, so knowing that is helpful. Have you any idea if it was even made locally to where you lived (or live)? (Knowing where a member lives sometimes helps to zone in on a particular country, at least).
Are you going to continue looking for more info? I'm sorry you didn't find it here - we have tried!
I'm so pleased you let us know about your vase though. If you have any other glass pieces that you'd like to know more about, here's the place to ask your questions!
