Actually it does but not for the reasons you might think. Vintage jewelry made of or with plastic falls into one of six groups: celluloid, casein, cellulose acetate, phenolics which include Bakelite, and acrylics which include Lucite. The words celluloid, bakelite and lucite have become so generalized that instead of referring to a specific material, often only a general group is meant. A thermoplastic is a plastic that has been shaped in some way cast, molded, cut, carved, whatever and then hardened as it cooled. However, if sufficient heat is applied to any part of it — and that could be as high a temperature as boiling water or as low as F from tap water or being left in the sun — it will soften again. Thus a thermoplastic is a substance that can and will become soft and malleable again or damaged via the application of heat.

Vintage Celluloid Jewelry

Celluloid is a highly flammable early vintage plastic which contains camphor. It is very lightweight and was later discontinued in favor of heavier more durable forms of plastic. Celluloid was one of the first plastics to be widely used in making jewelry. The material is derived from a natural plant fiber. It was originally developed in the s in England by John Wesley Hyatt who commercialized the use of celluloid.

Hyatt had experimented with cellulose nitrate, intending to use it to manufacture billiard balls.

The detachable shirt collar was invented in by a housewife in Troy, New York. Her name was Hannah Lord Montague. Her idea caught on and became a commonplace during the rest of the nineteenth century. Shirts were expensive and time-consuming to sew. The collar was the most likely part of the garment to wear and become soiled. Having a changeable collar solved a problem for many young men and their wives or mothers. Detachable collars could be made of linen, cotton, paper or fabric laminated to paper.

Linen and cotton collars were heavily starched to make them stiff. They were held in place by studs or buttons. Styles came in stand up, lay down or wing tip.

My good friend Delores loves shopping at Dogbotz Boneyard as she has been a collector of costume jewelry for a few years now. While chatting last week, Delores asked me about the use of plastic in vintage costume jewelry as she had recently discovered Bakelite, both in its colorful beauty and in its investment value. As there were three musical Andrews Sisters Patty, Maxine, and LaVerne who were established singers and radio personalities throughout the s and 50s, so, too, were there three plastics that made costume jewelry quite eye-catching and, today, often expensive.

Dating from the beginning of the 20 th century to the s, Celluloid is one of the earliest man-made plastics widely used in costume jewelry. Celluloid has certain characteristics that differentiate it from other plastics. In general, pieces made from Celluloid tend to be thin, light, somewhat brittle, sensitive to heat they crack and craze , and early Celluloid can be extremely flammable do not ever test with a hot pin! Celluloid is flexible.

It can be bent, twisted, and molded. When placed briefly in hot water, early Celluloid smells like camphor, while later cellulose acetate smells like vinegar. Celluloid jewelry should be stored carefully. Extremes of temperature, moisture, exposure to cosmetics or perfume, or lack of adequate ventilation can cause a Celluloid piece to begin to discolor, crack, or even disintegrate. A piece of Celluloid jewelry so afflicted is contagious to other Celluloid pieces; thus, it should be segregated from other Celluloid jewelry.

During the 19th century many scientists were experimenting with synthetic plastics in order to replace the expensive natural plastics such as horn, ivory, and tortoiseshell. It was invented by John Wesley Hyatt in to simulate ivory which was in short supply and needed for such items as billiard balls.

Soon the new plastic was being produced all over Europe and Asia, much to the relief of millions of elephants, tortoises and horned animals! One of the earliest uses was famously for movie and photographic film. Soon it was used for pretty much anything. It was very popular during the Art Deco period for vintage jewelry, dolls, hair ornaments and combs, dressing table sets, hat pins, buckles and buttons, frames for pictures and mirrors, toys, novelty charms, knife handles and other utensils.

Many Celluloid jewelry pieces survive, especially little brooches in the form of flowers, birds and animals. Dog brooches, especially terriers were very popular, I had one a while back which was a really cute Scottie dog with a nodding head. But it had one important flaw – it was highly flammable.

March 21, Application mad m 1a, There is a commercial demand for: tubes of mosaic structure for the bodies and caps offountain pens, pencils, and the like. When hardened, such an aggregateis cut to form tubes. Such l5 rods which are bored to form methods and means of manufacture ‘arefobviously very costly; the cost of such raw mosaic’ material being more than five times that V of the ordinary celluloid or the like of uniform texture or color.

Moreover, it is, of course, impossible to precisely predetermine the location of the different materials in a tube to be formed from such an aggregate; and particularly to predetermine the location-of any pattern with referenceto’the circumference of the tubes. It is the object and eflect of my invention to not only materially lessen the cost of manufactureof such mosaic tubes but’to precisely terials upon the outer surfaces of the tubes.

As hereinafter described,it is characteristic ‘of my invention that a tube is formedof inner and outer laminations of materials Which are different either in color or texture. Such tubes may be conveniently formed by rolling sheets of celluloid and the like upon mandrel’s. For example, acetone is “a suitable solvent celluloid and cellulose nitrate, and ethyl acetate, or a mixture of alcohol and ether, are suitable solvents for cellulose acetate.

In such a process of manufacture of the tubes; theinner and outer laminationsmay W be part of a continuous sheet or formed of and the like upon a lamination of the tube forced into an inner outer material in-the inner respectively indicated at 1 may be what is known as pearl celluloid ‘rarily rigidly connected. Said mandrel is preferably a cylinder separate sheets; However, tubes withrespec tively difi’erent outer and inner laminations may be otherwise formed,’for instance, by rendering thelaminati’ons tubular, independently of each other, and subsequently slipping one over the other.

The very word Celluloid is marked by the characteristics of an earlier period when ladies secured their hair in place with decorative combs and gentlemen strugled with the discomfort of stiff Collars. The story of Celluloid in fashion begins with waterproof collars and cuffs when it was introduced as an alternative to linen. Celluloid was a material that often pretended to be something it was not.

Celluloids are a class of materials produced by mixing nitrocellulose and camphor , often with added dyes and other agents. Once much more common, celluloid’s common contemporary uses are table tennis balls , musical instruments, combs, office equipment, and guitar picks. Celluloid originated in , when Alexander Parkes created Parkesine, generally considered the first thermoplastic. Celluloid was easily molded and shaped, and it was first widely used as an ivory replacement.

The main use was in movie and photography film industries, which used only celluloid film stock prior to the adoption of acetate safety film in the s. Celluloid is highly flammable, difficult and expensive to produce and no longer widely used. Nitrocellulose-based plastics slightly predate celluloid. Collodion , invented in and used as a wound dressing and an emulsion for photographic plates, is dried to a celluloid like film.
