Bakelite

Here is some history about Bakelite, information regarding Catalin and Galalith.

How to test and identify.

Bakelite history

Developed in 1907 by Belgian-American chemist Leo Baekeland, Bakelite was the world’s first completely synthetic plastic. Named "the material of a thousand uses," its exceptional heat resistance, electrical non-conductivity, and moldability revolutionized the modern manufacturing and electronics industries.

Bakelite jewellery emerged in the 1920s as the first truly synthetic, castable plastic. Championed by designers like Coco Chanel, it defined Art Deco and the Great Depression era. Today, it remains highly sought after by vintage collectors.

Identifying Bakelite

To identify genuine Bakelite, rely on its physical weight and unique chemical composition. First, check the weight—it feels surprisingly heavy and dense compared to standard modern plastics. Then, verify authenticity using a friction-heat smell test, a cleaning solution, or specialized polish.

Physical & Sensory Tests

The Tap Test: When you gently tap two pieces of authentic Bakelite together, they produce a deep, solid, distinctive "clunk" rather than a high-pitched click.
The Weight Test: Hold the item in your hand. Bakelite is a phenolic resin and feels noticeably heavier, denser, and more substantial than lighter plastics like Lucite or Celluloid.
The Hot Water & Smell Test: First be sure its not amber heat or hot water can crack amber. Run the piece under hot water for 30 seconds or rub it vigorously with your thumb until it gets warm. Immediately smell the surface. Authentic Bakelite gives off a distinct, pungent, burnt-rubber or formaldehyde-like smell

Testing with Simichrome

This is a very reliable way to identify Bakelite or Catalin

Testing Bakelite with Simichrome is a reliable, non-destructive method for collectors. With a cotton bud Rub a tiny dab of the pink Simichrome Polish onto an inconspicuous spot on the item. If after rubbing, the cream on the cotton bud turns a bright, distinct yellow , it is Catalin.

Bakelite is often confused by sellers claiming it is amber.

What to look for:

are all the beads the same color? (its not amber, the odds of finding a vintage cherry color amber necklace with all the beads looking the same in shade is almost impossible) are there any inclusions (no, then it is most likely not genuine amber amber is natural fossilized tree resin and will have some inclusions)

Catalin, Bakelite, Galalith,
The difference

Catalin, Bakelite, and Galalith are early, highly collectible plastics developed in the early 20th century. While Bakelite and Catalin are different forms of the same phenolic resin, Galalith is an entirely different material made from milk proteins.

1. Bakelite

Composition: A thermosetting phenol-formaldehyde resin, often containing fillers like wood flour, asbestos, or carbon black.
Colors: Typically opaque and limited to dark or dull colors (black, dark brown, dark green, deep red).

2. Catalin

Composition: Also a phenolic resin, but it uses different mineral fillers. It is a cast plastic poured into lead molds.
Colors: Renowned for vibrant, bright colors (butterscotch, cherry red, marbled yellow) and a translucent quality, especially around the edges

3. Galalith

Composition: A casein-based plastic made from milk proteins (curds) and formaldehyde.
Colors: Can be made to imitate natural materials like ivory, bone, and tortoiseshell, or dyed in various colors.
Use: Often called "French Bakelite" in the jewelry and button industries. It was frequently carved and shaped for Art Deco jewelry.
Properties: It is porous compared to synthetic resins and can swell or deteriorate if submerged in hot water
