|Henry Ford in a soybean field.|
Taken from a 1946 Ford Motor Company ad.
At the Ford Exhibit at the 1934 Century of Progress World’s Fair in Chicago, a dinner was held. The menu offered:
Tomato Juice Seasoned With Soy SauceAlas, no mention of soybean candles. There was once, however, a soybean car.
Salted Soy Beans
Celery Stuffed With Soy Bean Cheese
Puree Of Soy Bean
Soy Bean Cracker
Soy Bean Croquettes With Tomato Sauce
Buttered Green Soy Beans
Pineapple Ring With Soy Bean Cheese And Soy Bean Dressing
Soy Bean Bread With Soy Bean Relish
Soy Bean Biscuit With Soy Bean Butter
Apple Pie (Soy Bean Crust)
Cocoa With Soy Bean Milk
Soy Bean Coffee
Assorted Soy Bean Cookies
Soy Bean Cakes
Assorted Soy Bean Candy
Rumor has it that by 1935, every car Ford made contained a bushel of soybeans, and, at TheHenryFord.org, you can learn about the plastic that Ford made from soybean meal. It was so durable Ford could whack it with an axe, no problem. He had his picture taken doing this, so there is proof. A Ford ad from 1935 claims “We Paint Cars with Soy Beans.” In Greenfield, Michigan, Ford built a soybean lab and maintained acres of soybean fields. In 1941, Ford built a car completely from soybeans. This car had its skeptics, but, unfortunately, World War II came along, and the demands the war made on industry and resources put the kibosh on Ford’s fiddling around with soybeans. In 1947, at age 83, Ford died. But wouldn’t it be great if nowadays we could burn our soy bean candles in our soy bean cars while eating soy bean candy?
Ford was a chemurgist, a word that he and like-minded individuals came up with in the mid 1930s. From a 2003 article in the Journal of Industrial Ecology on the history of chemurgy, we find this explanation:
Basing the name of their movement on the root words for chemistry (chemi) and work (ergon), chemurgists contended that the chemicals found in farm products could provide industry with needed raw materials. … Chemurgists had three principal goals: to develop new, nonfood uses of existing crops; to develop new farm commodities useful to industry to grow in lieu of surplus commodities; and to find profitable uses for various agricultural wastes and residues. Moreover, because most chemurgists were unabashedly economic nationalists, most hoped their programs would drastically reduce U.S. dependence on foreign markets.I first became aware of the word “chemurgy” through the wax book by Warth. The word “chemurgic” appears toward the end of the section on beeswax.
The National Farm Chemurgic Council has reported that beeswax is being used in connection with the manufacture of at least four hundred articles—from ammunition, cosmetics, and medicines, to protective coatings on airplanes.I couldn’t place the word “chemurgic” nor fathom its meaning, so I searched online and found the Journal of Industrial Ecology article. Chemurgy’s emergence is linked to the experiences of and aftermath of World War I, including the Great Depression, and various chemurgy councils that sprung up from the idea had an impact which lasted, again, until World War II. After the war, interest in farm-to-industry “chemurgy” was difficult to revive and the various councils eventually disbanded.
Proponents of chemurgy varied in their intensity of belief. William J. Hale was, perhaps, an extremist. In his New York Times obituary of August 9, 1955, Hale is referred to as “the father of chemurgy,” and the Journal of Industrial Ecology article describes him as a “Michigan chemist linked by marriage to the Dow Chemical Company, and chair of the U.S. National Research Council’s Chemistry and Chemical Technology Committee.” According to the article:
… the chemurgists’ isolationist politics came under increasing scrutiny, and Hale’s writings, which included strong praise for the self-sufficiency schemes of Nazi Germany, became increasingly irrelevant …In Warth’s book, soy wax is mentioned in both the natural wax and synthetic wax sections. Although soybeans do produce a minuscule amount of wax naturally, it is only as a consequence of soybean oil being left to winterize, the oil then producing a wax that is “about 0.002 per cent of the original oil.” This is not the wax, of course, now marketed for candlemaking. That wax, as mentioned, got its start in the 1990s. Methods of creating a synthetic soy wax, however, were being experimented with much earlier. Warth refers to a paper written in 1934:
In the high-pressure hydrogenation of soybean oil Shinosaki and Kubo125 found that at 350° an almost entirely wax-like substance was formed. … The catalyst used in the hydrogenation was copper carbonate on infusorial earth … ”Could there have been soy candles at Ford’s soy dinner after all?
Today’s soy wax is created through this process of hydrogenation, and, from what I understand, it goes something like this. First, the oil is squished out of the soybean. Then, the oil is hydrogenated, meaning it is mixed with hydrogen. But, just as oil and water don’t mix, neither do oil and hydrogen. To make the mix work, a catalyst is required, a catalyst being kind of like the preacher at a wedding—they enable the joining of unrelated substances. As in 1934, today’s catalyst for soybean oil and hydrogen is copper, and a quick search online shows that to the candlemaker many different soy wax formulations are available. These formulas may include other waxes and what-not—recipes are, of course, well-guarded industry secrets. While one formula is said to work better for candles in jars and such, another formula will be better for molded pillars and another yet will prove superior for holding the candlemaker’s additives of color and scent. These waxes go by various brand names such as eco-this and eco-that and are designed to serve specific needs and demands of the commercial wax market—just what The Body Shop ordered.
In Warth’s chapter on synthetic waxes, the waxes are divided into eleven groups. Under “Hydrogenation of Oils,” among many others we find hydrogenated cottonseed oil, known as Coto Flakes, which sounded to me like a breakfast cereal. I could hear the ad campaign: Does your appetite wax and wane? Even it out with Coto Flakes! Coto Flakes was, in reality, used as a substitute “for palm oil when coating the pickled steel sheets in the manufacture of tin plate.” Apparently, it was far less likely to become rancid. We also find Opalwax, which was the brand name for a DuPont product produced by hydrogenating castor bean oil. Opalwax had many applications, including “ … impregnating and coating papers, fiber board, leather, cork and textiles to make them grease, oil, and waterproof, [and] as a lubricant for electrical insulation.” It was also “claimed to be of value in the manufacture of candles, rubber-coated fabrics, polishes and finishes, carbon paper, inks, cutting oils, and for waterproofing and air breaking of air plane wings.” I went online to see if Opalwax and Coto Flakes were still around. It seems they are not.
Soy wax is now fairly ubiquitous in the scented candle market as it is plentiful and inexpensive. The size of the soybean crop in the U.S. is second only to corn. A July 2017 article on AgWeb.com leads with “The world’s soybean crop has grown by leaps and bounds since 1990, growing 231%.” When it comes to soy, Henry Ford was ahead of his time.
