To use, dampen a cotton swab with 409 and rub it gently on the inside of the item being tested. If it is Bakelite, the swab will turn yellow. If a piece is lacquered, it may test negative with 409. Black Bakelite pieces often fail this test as well.

Read More »Curious about a flea market find? It could be Bakelite, a synthetic compound developed in 1907 by Leo Baekeland, a Belgian-American chemist. Widely considered the first synthetic plastic, Bakelite items are a hot commodity today among collectors of vintage jewelry and mechanical parts. With plenty of reproductions on the market, it's wise to learn various methods to identify Bakelite rather than finding out afterward that you have made a costly mistake. There are many ways to test valuable Bakelite pieces, and several of them require using only your senses. Until you get very comfortable identifying Bakelite, however, it's good to employ more than one of these tests. Some people who are well-versed in Bakelite identification recommend the hot water test as the standard when it comes to accurately identifying this form of plastic. In this method, the piece of plastic is placed under very hot running tap water. The heat from the water releases the formaldehyde-like scent of Bakelite. This test works well with bangle bracelets that are made entirely of Bakelite and is a very good way to confirm a piece once you get it home. But while this has proven an effective method of at-home testing, most consumers trying to verify vintage items don't have access to hot water when making buying decisions in the middle of a flea market.
