Lot's of people like obsidian and are willing to pay for it. Glass from fused sand created from meteor impacts is highly sought after and collectible, therefore of value.
Natural sapphires do cut glass, I'm pretty sure any natural/real stone/mineral can cut glass. I tried it with mine and it cut a piece of glass.........
The worth of sea glass greatly depends on the color and quality of each piece. Natural sea glass values range from the most commonly found such as brown, green and white to the more rare pieces such as red, orange and gray. I have seen single pieces of red sell for as much as $200.00. The more rare the color, the more valuable.
No it is a man made material.Glasses are typically brittle and can be optically transparent.The most familiar type of glass is soda-lime glass, which is composed of about 75% Silicon dioxide (SiO2), sodium oxide (Na2O) from soda ash, lime (CaO), and several minor additives. The term glass is often used to refer only to this specific use
No. Glass bottles will undergo physical changes in the environment such as breaking or sharp edges smoothing out (think seaglass), but the natural processes of chemical decomposition doesn't work on glass. The same goes for styrofoam.
Valadium is not worth much at all.
of course it is!
They could be. If you take it to a pawn shop it may be worth some dollars
sand and glass mixture
Obsidian is a natural glass.
some natural forces can cause glass to break
Glass is formed from sand or silica.
Glass does not "do" anything with heat. Glass is not a (thermal) insulator though.
Natural fibre
A diamond will cut glass.
Liquid silver is worth the same amount as solid silver. This is not its natural state, and it would have be kept at an extremely high temperature to remain liquid.
