Yeah, I think Granite can be drilled using copper tools and abrasives, as it has been reproduced.

Why dont you think it's possible for the Egyptians to have done it?
I don’t agree.

Those compounds are close to diamonds. Didn’t you say diamonds were not used ?…..
 
Clearly not, because even though the article you've been quoting for pages did it. You claim it can't be done.
Based on how hard granite is, how many cores I’ve drilled, I’m saying copper it too soft.

Core 7 is still very impressive for 3k years old though. That’s my point, they did things that shouldn’t have been possible

It has been done.

Are you accusing the Penn study where they drilled it using a wide range of abrasives and copper tools of being all lies?

You know, the study you've been quoting?

I’ve no doubt penn used copper.

Remember though, they couldn’t replicate core 7.

Even someone with your lack of critical thinking should take something from that….

They weren't trying to replicate core 7, not do they mention it at all. You haven't proven that they couldn't or that they didn't buy accident.

All you've proven is that you don't know wtf you're talking about.

Penn used copper tools and abrasives to drill a core into granite.
 
You posted a paper that says it is possible, copper tools with abrasives.
I posted a paper showing what penn said was possible but as above they couldn’t replicate it.

The paper was to illustrate what an achievement core 7 was. The cooper core drill was/is irrelevant.

The core would/is impressive today. Let’s see you and you’re titan core set reproduce it ?
 
I’ve already said that, and they can’t reproduce core 7.

And it’s “by” not “buy”

Are you getting mad now lol
You said that, but you make **** up. You said you can't drill granite with copper. You've given no details on what was so unique about core 7.

You did quote :rolleyes: Google AI summary saying it couldn't be reproduced :rolleyes: but that was quoting Reddit.
 
Core 7 isn't mentioned in the paper, at all. That was nothing to do with their experiments.
The granite core published by Petrie was made by the ancient Egyptians using a tubular drill. Note the similarity of the concentric lines (arrow) found on the core.

Which core are they referring to then ?

Core 7 is famous, I’ve told you 3 times now.

It’s hardly my fault if you don’t pay attention.
