Why can't it be one method and you are only presenting examples from each end of the quality spectrum?
That makes not sense at all. If its the same method, say a turning wheel then the signature is going to be much the same. If its not turning device then the signatures are going to be the same but different to the turned vases.
Still it does matter. Its the obvious circular strirations on the interior that matches machining. Just that alone points to some sort of turning device. It does not matter how the other vases were made or turned out. We already have the machining signatures.
Do they, the general archeology people I mean?
Yes. Even general articles on the predynastic and Naqada period mention some sort of turning was involved. Flinders Petrie who is the main archeologist who discovered most of these works mentions some sort of lathe was involved.
Archeologist don't hestitate to say well rounded pottery was made on a wheel. In the following well known article they mention the consensus that the potters wheel and the Bore stick were not around at the time of predynastic Naqada.
Then later when discussing the hard stone precision vases they state that some sort of rotary device was needed. They refer to the later wheel and Bore stick that are of Mid Kingdom wall paintings as examples.
So even though they acknowledge that the wheel or lathe was not around they still cite that these vases must have been made by some lathe or wheel because they are obviously made that way compared to other vases.
This is common that even though they know this tech was not available they still naturally explain that some sort of turning device was required to achieve such high levels of roundness. They just don't elaborate how this is possible.
Before the Pyramids
Egyptian Predynastic pottery was produce long before the introduction of the potters wheel. Each piece was thus almost entirely handmade.
Parallel lines on the interior of some vessels suggest the use of some sort of rotary tool.
Could be involved, or was involved?
Well was involved because they are using the idea that simple lathing can explain the good circularity. There was a period for a number of pages where we were arguing about how complex the lathing device would have to be.
Or that once a device gets the stone rotating it can be rounded with a quartz cutter and is not too hard to do. Or my dad used a lathe in the 1950s or they personally used a lathe and it can be done with simple lathing ect. This was a big part of explaining the roundness lol.
No, me saying that there might have been turntables does not mean that I'm arguing that they was necessary. What you state after your "thus" does not follow what precedes it. It is A source of good circularity and symmetry but not the only source of either of them.
I am saying you naturally referred to some sort of turntable because its logical and common sense to do so. We don't even know we are doing it because its such an accepted and natural conslusion to pottery or vases with high roundness. You think what could create such good roundness. You thinkl of a turning device and not the coil method or by chisel ect.
It would be perfectly fine if anyone found an predynastic Egypt potters wheel, it would even be cool and interesting.
Yes and it may be ;ike other discoveries such as GT that we have to push back our understanding of what level of knowledge and tech these ancients have.
I was actually thinking of another example that may be interesting to investigate. The electromagnetism and possible energy generation from the ancients. There may be some interesting discoveries. I am not saying there is anything to this. But that it would be interesting to investigate because well it would be amazing of true and would add strong evidence of adbanced knowledge.
