Is this radio really made of Catalin?
Many sellers sincerely believe they have a rare catalin radio. They may list their item on eBay with a question mark because they're not sure. You can usually spot genuine catalin because you'll see many bids on the item. It's still a good idea to train yourself to identify the real McCoy.
Catalin and Marblette are trade-names for slight variations on the original Bakelite chemical formula. During manufacturing, Catalin started out as a clear resin. Then dyes were added to give it various colors. Even with these colors added, light will still pass through Catalin. Use a pretty good light and see if it passes through. If it does, you are certainly on the right track. Light will pass thru Catalin. Even Black Catalin will offer a little translucence. It may appear a little green. Another test used by some is a heat test. Plaskon, Bakelite, Beetle, and Catalin won't melt. Although they may produce an odor when heated, but the smell test alone, and the heat test in general are not conclusive tests for Catalin.
Although some Catalin radios and other items may have been made very thick they may also be thin. Catalin is a poured or cast plastic which allows it to be made thick but in the case of Emerson Patriot radios of the early 40's Monsanto Plastic was the supplier of these Catalin cases and they have walls that are a little thinner than those made by Catalin Corp.
Catalin may be found with dramatic swirling, but also in solid colors. It's really important to know how to identify it, since it's often very valuable. eBay is a great place to study these items.
An important fact regarding many Catalin items is the level of discoloration that takes place. As Catalin ages, and is exposed to the environment and light it will change color, often darkening.
Produced in dozens of colors--solid and marbled--many have changed over time:
-white turned to cream corn
-turquoise turned to green
-pink turned to orange
-violet turned to brown
-blue turned to green
Professionals exist who can remove the discoloration, but many just like to enjoy them as they are.
Generally Catalin can be found in a wide variety of colors and color combinations. To see more Catalin items go to: Other Catalin Items |
