Think when some French company bought out Bakelite it was renamed to Catalin. Also think they started to make white and see through versions. Not an expert though so don't quote me on that.
The words "bakelite" and "catalin" are often used interchangeably. However, they are actually two different materials. Both are thermoset plastics made from formaldehyde. The differences between the two are in the fillers used, origin of manufacture, the opaqueness, and the colors available. Most bakelite jewelry that you see for sale is actually catalin.
Bakelite; This thermoset plastic made from phenol formaldehyde has fillers to make it more durable, stronger and less expensive. The filler could be rags, cotton, wood, carbon black - even asbestos. Because of this, reworking the product can make it harmful to your health. By and large, bakelite is very opaque. True bakelite colors are normally very dark because of the fillers. Bakelite is a US manufactured product, patented in 1907 by a Belgian chemist, Dr. Leo Hendrik Baekeland, working in New York. Most early uses of Bakelite were radios, handles for pots and pans, castings for televisions, toys, etc. Some was even used in coffins! Bakelite was manufactured between 1907 and 1927.
Catalin; is a thermoset plastic made from either phenol, melamine or urea formaldehyde, that normally has no fillers. It can be reworked and is usually very colorful. Catalin is also very translucent. Sunlight causes catalin to lighten over time. Catalin is also subject to shrinkage. When the patent for bakelite expired in 1927, the patent was acquired by the Catalin Corporation in the same year. The Catalin Corporation is thought to be responsible for nearly 70% of the phenol resins available today - thus the statement that most bakelite jewelry sold is actually catalin. Catalin jewelry production continued through the 1930s and 40s in abundance. With the introduction of lucite in the 1950s, the production of vintage catalin jewelry effectively ceased in the 1960s, although it is still possible to get reworked pieces which were manufactured much later than this date.
Hope that helps!
