Hi,
I have had this vase/bottle for ages. It has a great history with me, but I've never known even where to look to find out anything about it, so I am hoping someone here will have some ideas.

Back in the '70's, I don't remember exactly the year, but about 77-ish, probably, I found this while scavenging on the rocks/beach in Rhode Island. I was a kid at the time, about 8 probably. There had been an oil spill off the coast, and it was heavy crude that was spilled, which tends to sink to the bottom, become very plasticine and wash up in globs. Knowing nothing about it being unhealthy, I used to love to pick it up and look at the patterns in it. One day, I was walking along the rocky point of Bonnet Shores (giant granite rock outcroppings) just up into the mouth of Narragansett Bay from the Atlantic Ocean. I saw this sticking out, wedged in a big crack in the rocks. I picked it up thinking it was a glob of oil, but it was a glass bottle. I have kept it with me ever since. The best beach-glass find ever.

But no one has ever seen anything like it. I've included pictures, but they don't do it justice. Overall, it is just over 8" high, 6" wide at the bottom. The hole at the top is just under 1" across. It is thick glass, and heavy. It weighs about 2lbs. It is hand blown, I can see the scar at the bottom. It looks black at first sight, in part because it is all frosted from being beach-tumbled. It is actually bottle green, and there is a thin swirl of blue that runs horizontally, wrapped around, the middle. You cannot see that unless the light shines through it the right way. the base of the bottle/vase is flattened, curved under from the back and forward at the front, and there is rippling throughout the bottom ear/wave looking part. The opening is not quite level. I would love to have any ideas about what this might be. thanks for your help. I do have more pics, of the bottom, hole, etc, if they would be helpful.
