Franklin Furnace, also known as the Franklin Mine, is a famous mineral location for rare zinc, iron, manganese minerals in old mines in Franklin, New Jersey, USA. This locale produced more species of minerals (over 300) and more different fluorescent minerals than any other location. The famous mineral association (assemblage) from Franklin includes willemite, zincite and franklinite.
During the mid-to-late 19th century the furnace was the center of a large iron making operation. The Furnace mine which was adjacent to the actual furnace, was a 120+ foot vertical shaft just under Franklin Falls.
Other rare minerals include esperite, clinohedrite, hardystonite, and others. There are scores of minerals found only here, such as Johnbaumite (an arsenous apatite), McGovernite, etc.
Sterling Hill, a very similar ore deposit, is located a few miles away in Ogdensburg.

“We are not certain, we are never certain. If we were we could reach some conclusions, and we could, at last, make others take us seriously.
In this world nothing can be said to be certain, except death and taxes.”
—Benjamin Franklin (1706–1790)
“What the hammer?What the chain?
In what furnace was thy brain?
What the anvil?What dread grasp
Dare its deadly terrors clasp?”
—William Blake (1757–1827)
