This past Wednesday, I traveled to north Jersey, right below the NY border to the Sterling Hill Mine.

I was nervously anticipating the trip, not sure what to expect since this was my first visit to a mine ever. It was eye opening to say the least. Though this mine has been inactive since 1986, safety was the focus of the tour. Did you know women were considered bad luck and not even allowed into mines until into the 70s?? When my professor was a grad student, she had to wait outside until the boys were done. Now that's some bullshit.

Miners had it rough. In some areas, life expectancy was only 36 year old. Something to think about. Everything that isn't biological that you own is made of things that needed to be mined from the earth. All of the minerals and crystals that you covet are mined and used commercially for things you wouldn't ever guess. It all comes from somewhere.

This mine in particular was after franklinite, mined mainly for its zinc, but also its manganese.  Thanks to its abundance in this area, Franklin, NJ deemed themselves "The Fluorescent Mineral Capital of the World." And that's really the coolest part about franklinite, its fluorescence.

yeah, they're awesome! put a blacklight over your stash of minerals, you might have some. fluorite and calcite are pretty common and they both fluoresce

I am going to make my husband dig a black light out of our Halloween stuff to try it!

    Closet hippie. I have 3 sisters, 2 friends, 1 cat. I juggle those with the nagging need to make things.
