Odd open pontiled bottle.

[Jamdam]

I got this open pontiled bottle. Very thin glass. It stands almost 10" tall and 2" at the widest point. Odd funnel like lip. Light chip on bottom appears to be from the manufacturing. A slight haze inside light scratches but no chips. Tons of bubbles and character. What is it and when where these made or used. No embossing anywhere. Thanks for any replies.

Here’s an example I got from a New Orleans digger. He called it a truffle oil bottle. I haven’t any personal knowledge of the use.
