Caralin is a brand name for thermosetting plastic popular in the 1930s. chemically, its a phenol formaldehyde resin. catalin is a cas bakelite product, with a different manufacturng process (two-stage process) then other type of bakelite resins (without using fillers such as sawdust or carbon black). Catalin is transparent, near colorless, rather than opaque, brown, so unlike other bakelite phenolics it can be dyed bright colors or even marbled. this has made Catlin more popular than other types of bakelite. in the 1930-50’s it quickely replaced most plastic consumer goods.
Catalin cast bakelite is perhaps the most worldwide reconized plastic sed in fashion accessories and fine, expensive jewelry. Catalin has a soapy feel to it and when rubbed to produce heat, it is “possible” to be aware of a slight odor of formaldehyd – if you don’t kow what formaldehyde smells like; it can gave a pungent slightely stinging odor. it was, and still is used today to cure ( or pickle ) human organs for future analysis and in the embalming process since it stops degeneration of cell tissues.
You will note from the above description of catalin that the base product is near colourless. namy items were made with this colourless material which had a milky opaqueness and which slowly de generated on the exposed surfaces becoming a light yellow. it felt uncleand this can lead to a deep yellow or orange surface color being displaced and is what we see today as honey or pale yellow. This statement can be proved by scoringan unexpected surface through damage ( Chips etc) or from cutting, often seen when a large rod has been cut to make smaller ones.
It is this staining that can be removed with polishing with a range of cleaning can remove this again process taking the surface back to its original milky clearness.
The intended colors that were produced by this process invariably retain the original milkness, giving the product the now familar mottling showing through the colour which is so often used to describe the product. some sellers, not sure of exactly what they are offering for sale will call the item “catalin phenolic bakelite” and hppefully by using this “reference” document you will have a better idea of what it actually “might” be.
