A Belgian scientist named Dr. Leo Baekeland was responsible for the invention of Bakelite. In 1889 he immigrated the the United States, hoping for better career opportunities. In 1907 he was working as independent chemist when by accident he discovered the compound of carbolic acid and formaldehyde. When he tried to reheat the solidified compound he discovered it would not melt, no matter how high the temperature.
Bakelite has always been known as "the material with 1000 uses," and it surely did earn this name. It is now treasured for its unique, irreproducible beauty. When the Bakelite patent expired in 1927, it was acquired by the Catalin Corporation that same year. They began mass production under the name "Catalin". The Catalin Corporation was responsible for nearly 70% of all phenolic resins that exist today. Bakelite-Catalin was sold mainly to companies like Saks Fifth Avenue, Bonwit Teller, Woolworth's, and Sears. Much of the wealthy society fell into difficult financial times during the Great Depression and could no longer afford Tiffany diamonds or Cartier Jewelry. Bakelite-Catalin took up the market slack with its colorful carved jewelry adorned with rhinestones. This jewelry was within the reach of all, and its popularity grew from the poorest to the wealthiest in society. In 1942 Bakelite-Catalin stopped sales of their colorful costume jewelry in order to concentrate on the nation's wartime needs. The company produced thousands of products that found their way into the military. By the end of the World War II, new technologies for molded plastics had been developed. These new products consisted of plastics such as Lucite, Fiberglass, Vinyl, and Acrylic - all which were molded. And so Bakelite and Catalin become obsolete, except in the hearts of collectors who still pursue it today.
Shortly after that, he trademarked "Bakelite" as well as two other variations, "catalin" and "marblette" - which today are also referred to as Bakelite. Bakelite was the first completely synthetic plastic. Because of its durability and beauty, its uses were limitless. Its popularity grew very quickly, and within 15 years it had taken the world by storm. You could find everything from electrical plugs to ornate jewelry made from Bakelite. It was even used on the dashboard face of the Mercedes Benz car. Because of his invention, Dr. Baekeland is seen as the father of the present plastics industry. Bakelite could be produced in a wide array of colors, but the most common where white, brown, green and red. Pieces dating back to the 1920s-1940s has oxidized and developed a wonderful patina that is sometimes a completely different hue than the original color. For example, white often turns to butterscotch, light blue changes to forest green, and pink turns to orange. Costume jewelry from the 1920s-1940s Bakelite era is highly sought after. So how do you determine if a piece is genuine Bakelite? There are a couple of fairly simple tests. Although not foolproof, they work pretty well.
Smell. When Bakelite is heated it has a very strong odor which comes from the carbolic acid in the composition. On some pieces you can release the smell simply by rubbing them hard with your thumb and creating heat. Others will need very hot water to release the odor. On some the odor is so faint you may not detect it. Sound. When you tap two Bakelite pieces together they will make a deep clunking sound, rather than the higher pitched clack of acrylic or Lucite plastics. This test is the most unreliable because the density of the items affects the sound you hear.
Hot Pin Test. DON’T DO IT!!!!!! It will devalue the Bakelite piece considerably, and it may do serious damage to other types of plastic should the piece turn out not to be genuine. Also if the material should be celluloid, it is very flammable and can be very dangerous. If you suspect the piece may be celluloid, I recommend you do not conduct this test.
Formula 409 / Scrubbing Bubbles / Simichrome.This product works very well to test whether an item is Bakelite. Make sure the item is clean, wet the end of a Q-tip with Formula 409 then touch it to the piece. If the Q-tip turns yellow then the piece is genuine. If you believe a piece is Bakelite but it doesn't pass the 409 test, don't count it out. Sometimes polished Bakelite will not react or pass the test. Bakelite Testing Pads These work very well to test Bakelite. They are Wonderful these are great when you are out shopping, handy to have in your purse. You can test questionable vintage Bakelite pieces with ease, the pad is simply rubbed onto the piece and if a nicotine colored stain appears the test is positive. The only true test for red and black Bakelite naturally is the hot water test. These great little Bakelite testing pads can be used over and over, this 2 inch square pad can last a very long time.
