Harmony Borax Works
—Reﬁning Borax —
Borax - blacksmiths used it, as have potters, dairy farmers, housewives, meat packers, and even morticians. For centuries humans have exploited borax for many important uses.
The Process: Workers heated water in the boiling tanks, using an adjacent steam boiler.
Winching ore carts up the incline, they dumped the ore into the boiling tanks.
Workers added carbonated soda. The borax
They drew off the borax liquid into the cooling vats, were it crystallized on hanging metal rods.
Borax will not crystallize at temperatures above 120 degrees, so Harmony Borax Works stopped operating during the summer. To keep the crystallizing vats cool the rest of the year, workers wrapped them with water-soaked felt padding, visible in the photograph.
Lifting the rods out, they chipped of the now refined crystallized borax. To produce “concentrated” borax, the repeated the process.
For later transport, the workers bagged and stored the refined or concentrated borax in a barn that stood behind you.
