The history of Bakelite is quite fascinating, as are many of the other stories of how different products/materials came to be. Sadly, I do not own any Bakelite personally, but I hope to come across some jewelry one day.
This is a wonderful site where I found some very helpful information about the history of Bakelite.
"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.
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.
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.
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.
Bakelite is a thermoset plastic so it cannot be remolded with heat. To test if a piece is bakelite get a very very hot pin from an open flame source, then touch the pin to the item. If it is Bakelite it will not penetrate. It may give off the acid smell and it may leave a purple burn mark. If the pin penetrates or melts the plastic then it is not genuine Bakelite.
Use caution when doing this test as it can 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. If you proceed with this test be sure to find a very inconspicuous spot.
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. When ever you are conducting this test you should wear the appropriate safety equipment such as eye goggles and gloves.
- 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-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."I hope you enjoyed learning a little bit more about Bakelite and where it all started. When I read the history of different vintage pieces, it just makes me treasure them even more!
