Lawmakers this week introduced measures declaring the Io moth the state moth, Franklinite the state mineral and Thomas Alva Edison the state inventor.

Franklinite is named after the mineral-rich town of Franklin in Sussex County.

Associated with franklinite at Franklin Furnace, and found also at some other localities, is another member of the spinel group, namely, gahnite or zinc-spinel, which is a zinc aluminate, ZnAl2O4, with a little of the zinc replaced by iron and manganese.

This extremely white and fine pigment is prepared by the roasting and sublimation of franklinite, zincite, and other zinc-bearing ores largely found in New Jersey.

Herring was another American who invented celebrated safes, made with a boiler-iron exterior, a hardened steel inner safe, with the interior filled with a casting of franklinite around rods of soft steel.
