Identify bottleneck

Found this remnant on the Hudson River in Nyack, NY this weekend. I’m puzzled as to what its use was as I have never come across a bottle with such thin glass and double walled.


  • I am wondering if this might be the glass innards of a thermos bottle. A photo of the bottom of the base may help in determining its age.

  • That is a great thought! All I have is what was in my hand unfortunately. Thank you!
