Industrial Jewelry Molds

At the start of the 20th century, the runoff from chemical processes used in industrial jewelry production once turned the Woony a spectrum of unnatural colors. Copper and cyanide made the Woonasquatucket blue, nickel turned its waters green, and chromium cast the river a shade of yellow. 

During river clean-up efforts at the start of the 21st C, the Narragansett Bay Commission found old forgotten jewelry molds in the river, reminding us of 150-plus riverfront manufacturers that for a time made Providence the “jewelry capital of the world.”
