Common name of the man-made material is Smelted Quartz, also Cherry Quartz. It is not a natural volcanic glass, or a natural quartz, or a natural crystal formation. It is not a crystallized formation. Very pretty red and gold swirls in clear glass. Used for jewelry and carvings. You rarely see a jeweler missing fingers. Lapidary saws are diamond dust edged tools. People won't be losing hands and fingers working so close to these kind of blades - you'd have to hold your hand against it on purpose to get an abrasion, not a cut. The real danger here are the sharp edges of the material, and the dust if it is breathed or getting into eyes. Obviously it doesn't seem to be getting in anyone's eyes, but it would be nice to see proper safety equipment. Smelted quartz, a glass, is silica, "commonly found in nature as quartz" and "In many parts of the world, silica is the major constituent of sand." Utilized by many plants, including rice, most grasses, and also by some animals. so no, this process is not polluting the planet, or making dust that will be getting into the food chain and working it's way into our food. That's plastics. Ignorance begets stupidity. (There really is no excuse for posting ignorant comments when you can ask questions online and research to find answers.) However I do not know what is added to produce the red and yellow/gold coloring. Possibly "adding selenium (Se) for the red" color. Many colors are possible using many different chemicals, but because red is "associated with life-generating energy (the sun, blood, and fire)-and is the color of celebrations and prosperity" that is the material we see most often. The yellow material in the background is the same material with a different coloring agent. The list I saw online said "adding cerium (Ce) yellow". I do not know if these are correct, but naturally silica is white or clear. The colors are added. It is very likely the tailings are collected and recycled into the another mass like the one we see here. There's too much of it for them to throw away, and being glass, they should just be able to melt it down again. Sellers sell this and all glass as "obsidian" because that is the "industry standard" practice. Ask a single seller to change their wording to accurate descriptions, and they believe their product stops selling and people buy from others instead of them. Both buyers and sellers are to blame for the continued misuse of names. If you purchase, you should research first. If you sell, be responsible and honest. If you're not in China, don't overgeneralize an entire country of people based on common practices of many sellers.
My God, what awful work. Breathing in that glass dust, with no ear protection at all. And that guy at the grinding wheel: I'm surprised he has any fingers left.
They are going to damage their lungs sooner than later. When cutting glass or even handling wheat flour for baking, people must use masks to protect their lungs.
Behave, it's just red glass. Otherwise it's a perpetual heat source, they have thousands there. And safe, they can pick up molten glass with their hands.

Horrific working conditions
My God, what awful work. Breathing in that glass dust, with no ear protection at all. And that guy at the grinding wheel: I'm surprised he has any fingers left.
Sulphur mine in volcano core...WOW
디자인에 다양하게 사용이 가능한데 아깝네 공 만들기만 하시네요!!
사실은 유리가 가공이 굉장히 어렵습니다.
제가 봐도 어쉽긴하지만 고도의 기술이 아닌이상 공밖에 못만듭니다.
Those poor bastards beathing in all that glass dust.
They are going to damage their lungs sooner than later.
When cutting glass or even handling wheat flour for baking, people must use masks to protect their lungs.
I think that was salt not glass,if you are speaking of this dude th-cam.com/video/pFLc_3GCH5Q/w-d-xo.html
What volcano is this?
Team pottery..what an idea...!
Странно, у всех пальцы на месте..
Мастерство и удача .
Дай Бог им Всем здоровья .
Já cheguei dando like
Woaw ! But Bad for health
Looks like slag from a glass factory. No such thing as red clear “volcanic glass”. Nope
True. That piece doesn't look like it was formed by nature.
Hey, It's on TH-cam it has to be real!
Behave, it's just red glass. Otherwise it's a perpetual heat source, they have thousands there. And safe, they can pick up molten glass with their hands.
Truth!
Dimana ini?
Apa tidak ada video baru ya sampai video lama diupload terus jadi bosan nontonnya
可加工成什麼呢
I notice yellow stone in the background. Is that also volcanic?
Sulfur, probably!
