| This bottle had to be made between 1880 to 1914 to be one with manganese in it. I doubt it but possible. They also put several other minerals and metals in glass bottles. Led, Zink, copper and a few others. Placing it in the sun is one way to find out which. Don't spill anything cold on it when it,s in the sun. It could shatter. Try building a wooden ship in it. It's tedious work but if you've got the time it can be done. |
