			<content:encoded><![CDATA[<h2>Bakelite</h2>
<p><b>Scandal &#038; the Story of Bakelite</b><br />
<br />Bakelite hit the market in 1907, heralding the arrival of the modern plastics industry. Bakelite was the first completely man made plastic, as until then, plastics such as celluloid, casein, and Gutta-Percha all had as a base a natural material. It was developed by Belgian-born chemist Dr. Leo Hendrick Baekeland who started his firm General Bakelite Company to produce the phenolic resin type plastic. Bakelite was inexpensive to manufacture and extremely durable, and made its inventor a wealthy man.  In subsequent generations, however, the Baekeland&#8217;s family story was one of tragedy rather than triumph. In 1972 the schizophrenic great grandson of Dr. Baekeland stabbed his mother to death. Savage Grace, by Natalie Robbins and Steven M.L. Aronson, a book about the family and the murder, was a best seller when it was published in 1985.</p>
<p><b>Bakelite for Appliances &#038; Jewelry</b><br />
<br />Early Bakelite was used almost exclusively in the manufacture of radios, appliances and electrical components because it was lightweight, inexpensive, durable, moisture-resistant and non-flammable.  The limited color range of black, brown, and the occasional burgundy and dark green was appropriate for use as radio cabinets, vacuum cleaner parts, and electrical elements, but eventually, formulas were developed to produce the plastic in a range of appealing colors. Its ability to be carved and molded made it ideal for inexpensive jewelry. Early jewelry attempts to mimic more expensive materials like ivory amber, onyx, and jade, but by the 1930s, consumers began to appreciate the plastic for own qualities and Bakelite jewelry made its appearance everywhere from Sears Roebuck to Sacks 5th Avenue.</p>
<p><b>Colorful Art Deco Bakelite Gems</b><br />
<br />Artists and designers discovered the beauty and workability of Bakelite (and Catalin, a competitor who also produced a phenolic resin plastic). New technology created additional colors, and the plastic became available in scarlet, green, amber, brown burgundy, red-orange, and Kelly green and black and marbled.  By 1934, yet another plastics company had produced a formula for Bakelite in pastel colors including willow green, light blue, pink and yellow. Due to the unstable nature of the chemicals used in the pastel colors formula, these pieces are hard to find, and as such, are among the most costly of Bakelite jewelry.   </p>
<p><b>Bakelite Jewelry &#038; Values</b><br />
<br />Bakelite could be molded, carved, or laminated, and designers and turned to the material for brightly colored, inexpensive flights of fancy to adorn everything from wrists to waists. Necklaces featured beads in a variety of sizes and colors, sometimes terminating in carved or laminated pendants.  A popular choker style necklace consisted of pairs of bright red cherries on celluloid stems and leaves dangling from a celluloid chain (today $150-300.) </p>
<p><b>Bakelite Bracelets</b><br />
<br />Bracelets were stretchy, cuff, charm, wrap or tank-track styles. Stretchy bracelets consisted of beads or lozenges strung on elastic.  Cuff styles could be wide and deeply carved, or narrower bands intended to be stacked together. The band could be smooth, molded (usually in a geometric pattern), carved, or pierced.  Wrap bracelets were beads strung on wire, and tank-track bracelets featured overlapping semi-circular links.  A quick check on eBay turned up bracelets on offer in prices ranging from $50-300. Deeply carved, wide red cuffs seem to fetch the highest prices, followed by amber, then green. </p>
<p><b>Bakelite Pins</b><br />
<br />A variety of pins were produced, either whimsical figurals or geometrics.  The Art Deco love affair with the Scottie Dog was evident in the jewelry on offer.  Horses also had a strong presence, but pins of elephants, penguins, marlins, and cherries are also available.  Pins range in price from $118 for a lovely carved leaf, $130 for a carrot, $102 for a red horse head, and an almost shockingly low $18 for a classic Scottie in red.  </p>
<p><b>Bakelite Jewelry Affordable (Again)!</b><br />
<br />Prices reached almost ludicrous levels in the early 1990s, and the jewelry became so popular that other Bakelite pieces such as poker chips, Tootsie Toys and Mah Jong tiles were frequently fashioned into jewelry.  The market seems to have cooled, meaning that it&#8217;s once again possible to buy a fine Bakelite cuff bracelet for less than a gold one.</p>
<p> <i>Reference note by p4A Contributing Editor Susan Cramer, August, 2011</i></p>
<h2>Bakelite</h2>
<p>Bakelite is named after its inventor, Belgian-born chemist Leo Hendrik Baekeland (1863-1944). After emigrating to the United States in 1889, Baekeland dabbled in photography.  In the late nineteenth century, photographic paper was so insensitive to light that prints had to be exposed outdoors in sunlight.  Baekeland invented a more sensitive paper that he called Velox.  He sold the rights to George Eastman in 1899 for a million dollars.</p>
<p>Now independently wealthy, Baekeland bought a farm near Yonkers, New York and set up a laboratory in the barn.  He wanted to develop an insulating coating for copper wire, the kind of wire used to wind solenoids and motors.  In those days wire was coated with shellac, which was laboriously made from the shells of the lacca beetle that inhabited southeast Asia.  Shellac was expensive and in short supply.  Could Baekeland develop a synthetic substitute? </p>
<p>In 1907, he prepared a mixture of phenol, formaldehyde and lye which had the color and the consistency of honey.  Unexpectedly, the mixture hardened in its container, producing a solid whose surface faithfully duplicated the shape and the texture of its container.</p>
<p>It occurred to Baekeland that his mixture could be heated in molds to create objects of any desired shape.  Thus was born Bakelite, the world&#8217;s first synthetic plastic.  Baekeland founded The Bakelite Corporation to manufacture his material. </p>
<p>Bakelite is known by several generic names.  It is referred to as phenolic because phenol (C6H5OH) is the main ingredient.  Phenol is the preservative that is responsible for the &#8220;mediciney&#8221; smell of preschoolers&#8217; paste and is the &#8220;mediciney&#8221; ingredient in antiseptic mouthwash. </p>
<p>It is also known as thermosetting because the chemical reaction that creates the solid actually occurs while the molding compound is being heated in the mold.  Once the solid object has been formed, it cannot be softened again, unlike thermoplastics such as polystyrene that can be melted and re-used.  This property makes thermosets useful for objects that might become warm, such as housings for electrical devices or even handles for kitchen pots and pans. </p>
<p><center><br />

</center><br />
</p>
<p>Baekeland&#8217;s competitors also made thermosets, and the word &#8220;bakelite&#8221; (small b) became a generic term denoting phenolic from any manufacturer.  To further complicate things, The Bakelite Corporation later became a distributor of polystyrene, which was sold under the trade name Bakelite. </p>
<p>The original lump of Bakelite was a transparent amber-colored solid whose appearance Baekeland described as &#8220;frozen beer&#8221;.  A few products were actually molded that color, notably ladies&#8217; combs that were meant to simulate hand-carved tortoise shell. </p>
<p>Most Bakelite was made with additives that altered its appearance or mechanical properties. </p>
<p>Flock (short cotton threads) was often mixed with molding compound so that the threads would become embedded in the finished product.  The fibers improved Bakelite&#8217;s mechanical strength, much as steel reinforcing rods strengthen concrete. </p>
<p>The most common appearance for a Bakelite object was opaque black, which was produced by incorporating carbon black into the molding compound.  The ubiquitous black rotary-dial telephone was manufactured of black Bakelite. </p>

</center><br />
<br />
In the 1930s it became possible to make Bakelite in colors other than black by adding suitable pigments before molding.  This led to the use of phenolic for costume jewelry and other decorative items. </p>
<p><center><br />

</center><br />
<br />
Bakelite objects are manufactured by a process known as compression molding.  A pre-measured amount of molding compound is placed between two halves of a mold, which are then closed together.  Initial heating softens the compound to the consistency of putty.  High pressure forces the compound into every nook and cranny of the mold.  Continued heating promotes the chemical reaction that produces the solid object.  Automated molding presses could operate unattended, producing a finished object every 1-2 minutes. </p>
<p>Bakelite&#8217;s popularity began to decline in the 1940s as thermoplastics became more readily available.  The first major thermoplastic was cellulose acetate, which was made from a byproduct of the cotton gin.  Intricately-shaped objects can be fabricated by injection molding.  Molten plastic is forced into a mold under high pressure, where it cools and solidifies.  Since cellulose acetate was derived from an agricultural product, supply could not keep pace with the growth of demand.  After World War II, polystyrene (made from petroleum) quickly became the most popular thermoplastic. </p>
<p>The days of manufacturing collectible jewelry from Bakelite are over, but phenolics continue to be used for applications where heat resistance is required, such as electrical equipment or cookware. </p>

			<content:encoded><![CDATA[<h2>Baleen, Plastic of the 18th Century</h2>
<p>Baleen comes from a suborder of whales, Mysticeti, which includes, among others, humpback whales, gray whales, right whales and blue whales.  What sets these whales apart is baleen.  These whales do not have teeth, but have upper jaws filled with two rows of baleen plates fringed with fine baleen hair.  These plates are so closely aligned that they act like a comb or a sieve; whales pull water across them, catching the small plankton they feed on in the baleen &#8216;hairs&#8217;.  Baleen varies widely in size, as the sizes of the whales it comes from vary.  The individual plates can be as small as 2 feet, but as large as 12 feet long!  A single plate can weigh 200 pounds.  Baleen is often called whalebone, which is a bit of a misnomer.  Baleen is not bone, but rather keratin, the same protein that forms hair and fingernails in humans as well as horns and claws in animals.<br />
Archaeology suggests that hunting whales was crucial to the Inuit way of life as early as 1000 A.D.  In a landscape that offers so few materials, every part of a whale was used, including baleen.  Because of the lack of wood for fires for boiling water, baleen was softened by soaking it in urine.  Baleen had another property that made it valuable in the Arctic environment: it doesn&#8217;t not frost.  As a result, it was deemed useful for all sorts of utilitarian purposes, such as fishing lines and sled runners.  </p>

</center><br />
<br />
Europe was slower to realize all the potential uses of baleen, but as early as the 15th century, baleen, not whale oil, was driving the whaling industry.  Baleen was scraped to remove the fine hairs, and then boiled to soften it.  It could be softened to the point that it could be bent, molded and even stretched.  In this soft state, it was also possible to add dyes, most commonly black.  Baleen created items like riding crops and umbrella ribs and smaller bits of it were used to form cane heads and ladle handles.  (Baleen doesn&#8217;t conduct heat like metal either, so it made great handles and grips for objects that heated up.)  It was even used to bind violin bows and sword hilts.  Virtually every part of the whale was used, even the smallest fringe hairs on the baleen, which were used to stuff upholstery.  </p>
<p>Baleen&#8217;s price was closely linked to the fashion trends of England and Europe, being used for busks, pieces of a rigid material slipped into pockets in the front of a corset to keep it straight and upright.  As small decorative objects that could be carved and were placed in a hidden place near the heart, busks were common sweetheart gifts, often beautifully decorated with delicate carvings.  Baleen&#8217;s flexibility and durability also made it perfect for forming the hoops in hoop skirts.  Baleen&#8217;s price was roughly at its highest when hoop skirts were at their widest.</p>

</center><br />
<br />
As the whaling industry declined and better, cheaper plastics were developed, the use of baleen faded.  After the last quarter of the 19th century, most baleen appears in small souvenir objects from the Inuit and Yupik cultures of the Arctic.  As tourism in the region open up, handcrafts helped support the people who lived in these harsh regions.  Carving had long been a tradition, and baleen objects occasionally appear, but more often, baleen was used to inlay ivory carvings.  Basket weaving was also introduced, using small strips of baleen, and many finely woven baskets with carved ivory finials survive today.</p>

<p>Lenticular means, &#8220;1. shaped like a biconvex lens; 2. of or relating to a lens; 3. convex on both sides; lentil-shaped.&#8221;</p>
<p>In the world of collectibles, &#8220;lenticular&#8221; usually refers to a type of printing that creates a three-dimensional image through the use of a lenticular lens.  The resulting images reveal changes in depth or motion as the viewing angle changes.  (&#8220;Lenticular&#8221; doesn&#8217;t refer, despite the frequent use, necessarily to the image, but to the use of the lens effect.)</p>
<p>The technology, invented in the 1940s, was often used to create little optical illusion toys found in Cracker Jack boxes (the winking eyes, for example), but as the technique has evolved and improved, it&#8217;s found a home in the movie industry.  Lenticular printing creates those nifty movie posters that appear to move and change as one walks past them, changing the viewpoint, the kind of posters that might show a Dr. Jeckyll who morphs into a Mr. Hyde as you walk past.</p>
<p>The effect is achieved by combining multiple images with plastic that has integrated molded lenses and working with slices of the images to create a layered, complex effect.  For more information on the details of lenticular printing and the variety of formats, see <a href="http://en.wikipedia.org/wiki/Lenticular_printing" target="_blank">http://en.wikipedia.org/wiki/Lenticular_printing</a>.</p>
<p>Artists also work with lenticular lenses to create images like the one below.  The following are three views of a lenticular work by Yaacov Agam.  (p4a item # <A HREF="/Agam-Yaacov-Agamograph-Print-signed-proof-16-25-Untitled-Stars-13-inch-D9766397.html" target=_blank>D9766397</A>)<br />

			<content:encoded><![CDATA[<h2>Frederick C. Durant III</h2>
<p>Frederick C. Durant III was a key advisor to the U.S. military, intelligence, and civilian space-flight programs of the 1950s and 1960s. He served as president of the American Rocket Society in 1953 and president of the International Astronautical Federation (IAF) from 1953 to 1956. During the 1950s he worked for several different aerospace organizations, including: Bell Aircraft Corp., Everett Research Lab, the Naval Air Rocket Test Station, and the Maynard Ordnance Test Station. He later became assistant director of astronautics for the National Air and Space Museum of the Smithsonian Institution, in Washington, D.C., helping to launch the modern facility that millions of visitors tour each year. While at the Smithsonian, he was tapped to serve as the aerospace historian for the Encyclopaedia Britannica.</p>
<p>In the 1950s, he became one of the most respected independent advisors to the U.S. government on aerospace technology. He served on a Central Intelligence Agency panel in 1953 studying the possibility of extraterrestrial spacecraft as a potential threat to national security, co-authoring a report that concluded there was &#8220;no evidence that the phenomena indicate a need for the revision of current scientific concepts.&#8221; In 1954, he penned an article for Aviation Week magazine titled &#8220;Space Flight Needs Only Money, Time.&#8221; As president of the IAF, he told delegates at its 1954 convention in Innsbruck, Austria, &#8220;The feasibility of space flight is no longer a topic for academic debate but a matter of time, money, and a program.&#8221;</p>
<p>That same year, he was recruited to participate in the first civilian-oriented effort to put a satellite into orbit. Led by Wernher von Braun, the team developed a concept called Project Orbiter, which later served as the foundation of the successful Explorer I mission launched on 31 January 1958.</p>
<p>Durant was a long-time friend, confidant and supporter of Clarke&#8217;s. They corresponded and spoke by telephone frequently. The warmth of the friendship between Clarke and the Durant family is evident in the content of the inscriptions of these books. These books offer important associations between two dear friends, each a leader in his field.</p>

<p>Patent models are unique to a brief period of American history, when U.S. patent law required that all inventors submit a scale model of their invention in order to be granted a patent. With the recision of those laws in the late 1800s, models were no longer required, and the collections of the Patent Office&#8217;s 19th century models were placed in storage until budget constraints eventually forced the government to dispose of them, pursuant to an Act of Congress. </p>

<p>Electric stock tickers were invented in the 1860&#8242;s as an extension of existing telegraph services.  The early models were much improved by Thomas Edison but continued to be manufactured by several different companies.  Typically the tickers were provided to subscribers who paid approximately $6.00 per week to receive updated quotes on the stock and gold markets.  The tickers were widely used, with over one thousand at the New York Stock Exchange alone by 1880.  The usefulness of stock tickers declined as other forms of communication were developed, but they remained fixtures of the investment world until the World War II era.</p>

			<content:encoded><![CDATA[<h2>Roycroft &#8211; New York Arts &#038; Crafts Community</h2>
<p>After visiting William Morris&#8217;s Kelmscott community of artisans, charismatic businessman and writer Elbert Hubbard (1856 to 1915) embarked on his own version in East Aurora, New York. His Roycroft community, America&#8217;s only Arts &#038; Crafts campus, began in 1895 as a high quality leather bookbindery and publishing house. The name came from two 17th century London printers. The community&#8217;s large and prominently displayed mark, the orb and cross with a capital R in the bottom of the orb, was derived from a group of 14th century monks devoted to illuminating manuscripts. From its inception, Roycroft emphasized handwork, innovative design, the finest materials and low production.</p>
<p>Hubbard expanded his Roycroft community from leatherwork to furniture (1896), iron (1899), copper (1902), lighting (1905) and jewelry (1908). After Hubbard perished when the Germans sank the ocean liner Lusitania in 1915, the community remained together under his son, Elbert &#8220;Bert&#8221; Hubbard II. Bert&#8217;s 1919 catalog showed an impressive array of leather goods, lighting and metal accessories, but quality suffered after 1925. Roycroft was bankrupt by 1938. </p>
<p>Roycroft furniture in quartersawn oak, ash or mahogany, was massive and austere. Or as Elbert Hubbard described it: &#8220;Simple, solid, substantial and rarely beautiful.&#8221; Among its distinctive features was the tapered leg ending in a bulbous foot (the Mackmurdo foot). Compared to other Arts &#038; Crafts manufacturers, Roycroft&#8217;s furniture production was quite small. Collectors seem to prefer furniture marked &#8220;Roycroft &#8221; in script.</p>
<p>Metalwork creativity peaked from 1909 through 1911 with the collaboration of designer Dard Hunter (1883 to 1966) and metals artisan Karl Kipp (1881 to 1954). Their copper and German silver work is especially desirable. Although vases and other forms came in a variety of metals and finishes, collectors prefer Aurora Brown copper.</p>
<p>Collectors have long noted the unity of design among Roycroft books, leather, glass and metals. That consistency and recognizable style was an important contribution of Dard Hunter. </p>
<p>Hunter&#8217;s stained glass and oak table lamps and Karl Kipp&#8217;s classic metal lamps, especially the popular &#8220;helmet lamp&#8221;, are the shining stars of Roycroft lighting. Whether from Hunter, Kipp or another Roycroft designer, all intact Roycroft lighting should be regarded as a rare commodity. </p>
<p>Roycroft produced a large inventory of leather: desk sets, bookends, circular plant mats, wallets, handbags, even clocks. Because leather was considered utilitarian, more like shoes than art, many of these items have been discarded.</p>
