What's this? Just a 5,700 piece of gum. Not spearmint gum but rather a black-brown pitch, boiled down from the bark of a birch tree. People of the time might have chewed this to soften it to use as glue for tools. Or maybe even to treat an infected tooth. 📸: Theis Jenson https://t.co/PoQGcwp4tV — PolitiTweet.org
