just read an article somewhere that said there’s now a field tool archaeologists can use to pinpoint the source of the flint in minutes.
I don’t know. maybe google archaeologist flint field tool for the article
No, not flint. Obsidian. While obsidian is often wrongly called flint it's entirely different. Obsidian is natural glass created by volcanic action. Flint, jasper, chert etc. are formed in different ways and have different properties.
