Amber Bakelite: Is the reproduction of true amber in a celluloid plastic: Plastics in some form or other have been used in jewelry for many years. Celluloid was the first known plastic, invented in 1868 by John Hyatt. Then in the first part of the 20th century, casein (made from a milk protein) came along. He found that once it was cast, it could not be melted. The Great Depression of the '30s occurred. Money was scarce; women were looking for an inexpensive way to refurbish their old wardrobe and give it a new look; bakelite was the answer. One could find this unique jewelry in almost any color: red, green, and butterscotch being the most common. Bakelite jewelry added a cheery note to a bleak time in our history. Bakelite was used to imitate tortoiseshell, amber, and even gemstones. It was dyed to imitate coral and looked so believable that it often has to be tested to tell the difference. Bakelite, as was mentioned earlier, was often used to imitate amber. A lot of jewelry on the market today that is thought of as amber is actually bakelite. The one conclusive test is hot needle test. When a red hot needle is placed on a piece of bakelite, the material will not be penetrated; whereas, true amber will melt and release a faint piney odor. This is a destructive test but when in doubt it is the only test I know that is accurate. If you must know, please find an inconspicuous place on the specimen to do your testing.
Bakelite can be considered a resol.
The chemical formula of bakelite is (C14H18O5)n, where n represents a variable number of repeating units in the polymer structure.
Bakelite jewelry is an antique. With many different designs and styles, there are many options one might choose from. One can find information on Bakelite written in an easy-to-understand format at the "About" website.
phenol and formaldehyde!!!
Clean and dry Bakelite is a such a good insulator it would not be possible to use it to make a conductor of electricity.However if the piece of Bakelite was sprayed with water all over and a high enough voltage was applied to it, the water (not the Bakelite) would conduct electricity.Another possible answer is that if the Bakelite was made as thin as, say, some cigarette paper, and if a very high voltage was put across its thickness, the Bakelite would then break down and it would no longer be a good insulator. The burnt Bakelite could then conduct an electric current. Probably several hundreds or even thousands of volts would be needed to do that, but the resulting burnt stuff is not the same material as the clean and dry Bakelite we started with!The simple answer is bake it in a very hot oven (e.g. ≥500F) until it chars. The carbon in the charred Bakelite conducts.Warning: the charing process will generate smoke, which will both trigger your smoke alarm and make breathing very difficult! Please don't try this.

Yes, bakelite is permanently used.
Very expensive if it's real Bakelite
Bakelite is made by mixing carbolic acid with formaldehyde
Bakelite jewelry is basically vintage jewelry made from bakelite, the very first type of plastic that enables molding once heated. Bakelite is easily colored and can also be carved, which is why bakelite jewelry often depicts flowers and other colorful designs.
The thermal conductivity of Bakelite is typically around 0.15-0.25 W/m-K, which means it is considered a relatively poor conductor of heat compared to metals. This property makes Bakelite useful for applications where thermal insulation is desired.
Bakelite is a plastic made from phenol and formaldehide. It is a polymer.IUPAC name for bakelite is, polyoxybenzylmethylenglycolanhydride.
Bakelite was a form of plastic in the 1940's and 1950's in the United States. Bakelite means that the particles to make the plastic were baked and melted. Bakelite is also a very breakable plastic, almost like a ceramic.
Leo Hendrik Baekeland invented Bakelite in 1907. =)
Bakelite was prepared for the first time by Leo Baekeland in 1907, in Belgium.
yes bakelite waste are recycling & reuse +91 99799 53535
Leo Baekeland patented Bakelite.
