Additional comments.
1. Borax,
also known as sodium borate, sodium tetraborate, or disodium tetraborate, is an important boron compound, a mineral, and a salt of boric acid. It is usually a white powder consisting of soft colorless crystals that dissolve easily in water.
Borax has a wide variety of uses. It is a component of many detergents, cosmetics, and enamel glazes. It is also used to make buffer solutions in biochemistry, as a fire retardant, as an anti-fungal compound for fiberglass, as an insecticide, as a flux in metallurgy, a texturing agent in cooking, and as a precursor for other boron compounds.

9. Old Harmony Borax Works " White Gold "
Though steeped in legend, the frenzied search
for gold and other materials in Death Valley
produced few fortunes. Borax, the "White
Gold of the Desert," ranks as the valley's
most profitable mineral.
Harmony Borax works, in front of you, was one of Death Valley's first borax operations. It operated from 1883-1888. The 3/8-mile interpretive trail takes you through Harmony borax works. Picture: A 20 mule team at the Harmony Borax works about 1885. Some "20 mule" teams, like this one, had varying numbers of animals.

12. Twenty Mule Teams
For more than a century, the 20 Mule Team
has been a symbol of the borax industry ---
on product labels, in history books, and on
television. The status is well- earned; mule
teams helped solve the most diffiult task that
faced Death Valley borax operators --- getting
the product to market.
The mule teams pulled loads weighing up to 36 tons (33,113 kg), including 1,200 gallons (4,545 l) of drinking water. The rear wagon wheels were 7 feet (2.1m) high, and the entire unit with mules was more than 100 feet (30.5m) long. (Death Valley National Park)

15. Vintage Postcard - Typical Twenty Mule Team Outfit
During the 1880's, the twenty mule teams hauled borax from the refinery at Harmony Borax Works to the railroad at Mohave, California, 165 miles away. The twenty mule teams hauled loads of 36 1/2 tons and made the trip to Mojave in 10 days, maintaining almost timetable precision. The triumph of the twenty mule teams over the harsh desert was tremendous, but brief. In 1888 the great wagons and the twenty mule teams made their last trip out of Death Valley.

16. Vintage Postcard - Old Harmony Borax Mill-Death Valley, California
The ruins of the old mill, a few miles north of the Furnace Creek Ranch, which was in operation from 1883 to 1987. A 20 mult-team could haul 46,000 pounds of borax and its own water and hay on the arduous ten day, 165 mile trip to Mojave via Wingate Pass. Truly one of the great legends of the West
