Many years ago, this stuff we dug out of the ground and was highly prized.
Made this area quite valuable and influential at more than one point in history.
Still plenty of it around 😃
@RunningInCircles what's this? Obsidian?
@Kurohitsuji
Flint, so similar.

Worked in the same way, and has similar uses.
I actually wear an obsidian knapped pendant on a bit of leather as a necklace. Made it with a Japanese delegation that came across as part of an exchange with our local museum. Kind of a flint/obsidian fusion 😃
@RunningInCircles I see 🙂
