They ground up metal into fine dust and mixed it with glass. That's hardly profound. Today, we understand the actual scientific reasons these things happen, that doesn't mean they did, or that they did these things with the intent of creating such a result.
Old blacksmiths were able to form carbon nanotubes in steel. That does not imply they designed their method in order to create nanotubes, nor does it imply they were even aware of the existence of such a thing.
Same thing with maya blue, there isn't any mystery to it, we know exactly how to make it, and it's a simple process. It's properties are result of its ingredients, not magic of the maya. The ability to produce such a simple product doesn't imply you are aware of chemistry to the point where these ingredients were combined specifically to produce the properties that happen to exhibit.
These artifacts are definitely cool and interesting, but they in no way imply any sort of advanced ancient knowledge or abilities.

Very interesting. I watched a show the other day on one of the discovery channnels, possibly what the ancients knew? Anyways, they had a thing on roman "caged" glass which is what that cup would fall into and how they aren't quite sure to this day how it was done. The one guy who had come up with a theory on how it was done was using basically a diamond bladed dremel to replicate the caged glass look . The question that raises is where did they get the diamonds from ? As they said on the show , at the time the only place they could have gotten diamonds from was from India . Anyways, very interesting thanks for posting

The topic is quite misleading!
Using particles or creating particles of nano size is one thing.
Using created newly at a nano scale is another.
The Romans didn't create anything at a nano scale - they just reduced the gold etc to a nano scale.
If they had manipulated the structures of the material to create other structures at a nano scale, then it would be nanotechnology, but when its just reduction to nano scale, it aint.
There is also nothing that says they didn't understand what they were doing. We have no idea if they did this intentionally or otherwise.
It also doesn't imply they didn't.
I do not know much of the Maya blue only what the member above posted. Either way it is still interesting esp since you are taught that they were basically cavemen and didn't know anything yet they knew a lot for their time. It may not be up to our standards but for the time they were "advanced."
I agree they are cool and interesting but how do we know they don't imply advanced knowledge? I think our ancestors were a lot smarter and advanced than we give them credit for. Just because their advancements don't equal ours doesnt mean for their time they weren't advanced.
Thanks for the reply. I appreciate a skeptical reply to this.
