If you'd bother to watch the video, he (Ben with UnchartedX) explains that it would be impossible to create these things on lathes, even modern ones.

I don't care what some blogger explains. I know that I can do it.

Truly, these vases could only be produced in a computer, with design software, and manufactured with highly precise sophisticated machines

It's a bullshit. Right before me I have a glass made from stone, something like that - http://kamnerez07.ru/shop/product/bokal-d60-115 I don't know how that stone named in English, in Russian it is named змеевик. Hardness is just 1-2 below hardness of granite. You could also buy similar glasses from onyx, which is harder than granite, and other stones.

IDK, hardly this "ancient super advaced technology" of making stone glassware preserved only in Ural mountains region of Russia. I know similar things manufactured in Iran and Pakistan. If some dude from youtube could not do that, then it's only his ignorance, nothing more.

My glass is perfectly round, it was made on simple lathe, basically similar to simpliest wood lathe, but with diamond cutting disc instead of chisel. Inside is taken out with diamond ball mill. Stock is rotating slowly, diamond cutter rotates fast. It is possible to make partial arcs on surface (for handles, f.e.) rotating stock by incomplete turn, leaving some stone intact.

I could easily make similar granite vase on my metalworking lathe using dremel equipped with diamond disk instead of regular cutter. Will took some time and water, but absolutely nothing exceptional. High roundness is guaranteed.

In ancient times such things highly probably was made on hand-driven lathe of basic construction with rotating bronse disk/ball with sand melted in as cutting tool. Water was used for cooling and dust removal. Two slaves, one to rotate bronse tool at high speed with bow string and other to pour water was handy. Master slowly rotate stock in lathe by one hand doing cutting with rotating tool with other hand.

Once upon a time, being child I was very enthusiastic in all that "advaced ancient technology" bullshit too. But with time, I got a knowledge and expirience of how things work and how they made. I learned to work on different machines and use different tools. And now, all that "advanced ancient technologies" are nothing more than simple job done with simple tools. Tools simplicity just made job longer, not less precise. And ancient people had a lot of time. They didn't have twitter and netflix, so had to find some other ways to occupy themselves.
