Greetings. I am new to this forum!!
and a collector of agates and jades

I came in possession of two of these tubes, having no idea what they are
I did manage to get some sound out of them, by blowing them like trumpets
and someone suggested they may be pipes of sorts

I wonder why you say its natural glass, the first thing I thought is that they are made of crystal
silicon dioxide is what quarz is made of not glass afaik
[pubchem.ncbi.nlm.nih.gov]

do you mean natural glass is just a name for quarz? do you you know their hardness on the moh scale?

you have the most wonderful collection I have ever seen and would very much like to find one or two more
like the twisted ones

they are beautiful objects and will keep me wondering and staring at them for some time.....
