Just a community for everyone to share artifacts, reconstructions, or replicas for the historically-inclined to admire!
Generally, an artifact should be 100+ years old, but this is a flexible requirement if you find something rare and suitably linked to an era of history, not a strict rule. Anything over 100 is fair game regardless of rarity.
OTHER COMMS IN THE HISTORYVERSE:
This was a fascinating article, thanks for sharing it! I actually got into stained glass really heavily recently and that's something I've run into and actually have used at this point: dichroic glass. What an interesting and beautiful effect! It's absolutely wild to see these mfs all the way back that far in history figuring out how to make this stuff. To the common person back then, it would have appeared to be some sort of wizardry i would think. Hell, i can't help but think that stuff still looks like wizardry today, lol.
