Looks like glass slag.

Please start doing a little testing yourself, musse, OR find someone locally where you can bring these unknowns and they can test them for you.

Glass feels warmer than stone when you touch it to your upper lip or forehead.
Hardness?
Fracture?
Streak?
Resistance to muratic acid?
Polariscope reaction using a laptop?

When you can supply some real information, not just pictures, post. Otherwise you are wasting your time and my bandwidth.
Thanks for understanding.

It is often impossible to identify an unknown from a picture.

More important than learning how we run our site, might be YOU learning to identify the wares you are selling.
There are a couple of free courses on the left side. :D

Have you learned how to identify your fiber optic glass with magnification yet?

its almost impossible to identify from picture, unless there are useful picture from magnification, but judging from your pictures and melted area there is good chance that is glass slag,

I'm also convinced it is glass slag. Might be from iron works or other melting of ore...

l done the test with the lips, and its cooler than glass.... l have put Hydrochloric acid on the item, no reaktion. and if its glass the acid will not make a reaktion. and have taken a close up picture, hope it will help.

I still think it's glass slag. It can be very pretty and many things can be made with glass slag:
Usually starting something like this

you end up with
Image
and
Image

But in itself it is not very valuable....it's what you can do with it.

silica glass does not react to Hydrochloric acid, but Hydrofluoric acid reacts with glass
