Waylande Gregory

China Suppliers


Major artistic impact

Waylande Gregory is one of the most influential ceramic sculptors of the 20th century, who had helped to shape the Art Deco period in America. Artistically, he had developed much of the art-deco sculptural visual vocabulary in American art. In one of his more notable pieces, Salome, the horror of the decapitated St. John the Baptist is secondary to the lyricism of the near linear rhythm of Salome dance of the seven veils, expressive of pure form and motion. He combines both the erotic dance of the seven veils simultaneously with the decapitated head of St. John on a silver platter. Unlike his contemporaries at Cowan studios who followed in the footsteps of Austrian modern pottery exemplified by the Wiener Werksttte, Waylande Gregory sought to create a distinctly American form, for instance, his second sculpture of Henry Fonda, capturing in essence what he felt were the best American traits.

Technically, his most direct contributions include development of methods for the creation of monumental ceramic sculptural works, and the development of revolutionary glazing and processing methods. After he had moved to New Jersey and begun to work with the large kilns at Atlantic Terra Cotta, he began to develop new techniques which made monumental ceramic sculpture possible. Prior to Waylande Gregory, ceramic sculpture was limited in size due to the tendency for clay to slump after being formed without being supported by an armature of metal or wood. Other methods included sculpting the entire piece in clay and then going back and hollowing out the clay on the inside. This would lead to problems with sagging during firing, and tendency to crack. As a result, there were many limitations to the prior two techniques. By using a honeycomb method of building up the ceramic sculpture from the inside out, similar to the way that wasps build up their nests, he was able to form the sculpture as a self-supporting whole prior to firing, and his sculptures would go through the firing process successfully without cracking. Unlike other ceramicists, who would fire the sculpture to bisque, and then glaze, he would form, glaze and then fire the sculpture only once for the finished art work. nursery decoration

He never used factory-made glazes, grinding and mixing all of the glazes himself, carefully controlling firing temperatures as well as kiln atmosphere to achieve the effects that he desired. Among his innovations are compressing of glaze powder into a crayon for sfograffito, and a patented process for fusing glass and ceramic together in a crackle pattern. stocking holders

Early life advent wreath

Waylande Gregory was born in Baxter, Kansas in 1905. His mother was a concert pianist and his father a farmer. From an early age he had shown precocious artistic talent, beginning with small sculptures of animals in earth, as well as prodigious musical talent, even composing his own pieces. He at one time declared that he would no longer play pieces by Bach but only original pieces by Waylande Gregory.

In 1913, his mother moved to Pittsburg, Kansas in order to gain better educational opportunities for her 3 sons. At age 11 he was enrolled at the laboratory grade school at State Manual Training Normal, a teacher college, where he was taught by student teachers who were under supervision. State Manual Training Normal would later become Pittsburg State University of Kansas, studying crafts including carpentry and ceramics.

Adolescence and early adulthood

By the age of 14, he had made a bust of the school principal in only six sittings, as well as a ceramic statue called The Spirit of Athletics which is a composite of the best parts of his three classmates. While in high school, he had won awards for sculpture at the Kansas State Fair. After high school he had moved to Kansas City to attend the Art Institute, but immediately began to receive commissions for the sculptural decoration of the administration building at the University of Kansas in Lawrence, a statue of Pan for a Kansas City park, and a plaster relief sculpture for the Masonic Temple Building in Wichita. While at the Art Institute, he attracted the attention of Lorado Taft, a gay sculptor, primarily in bronze and marble, academically trained at the cole des Beaux Arts in Paris, who already had a reputation as a mentor to other American sculptors such as Janet Scudder. Lorado Taft had asked Waylande Gregory to be his assistant and to join him at the Art Institute of Chicago, at Midway Studios. For two years, he studied with Taft on and off. Taft would also bring him to Europe, to study classical Renaissance sculpture as well as to visit other artists in Europe. His experience with Lorado Taft would lead him to begin thinking of ceramic sculpture on a monumental scale.

In the meantime, at age 20, Waylande Gregory would direct the decoration and design of the Missouri Theater, the Hotel President in Kansas City, and the bas relief panels at Brandenburg field at Pittsburgh State University (Kansas). His most famous work at the Hotel President was the Aztec Room, the hotel's dining room, which he had decorated in Mayan plaster-of-Paris reliefs as interpreted in an art-deco idiom. Beneath the circular calendar, he had placed a replica of an Aztec altar which had recently been excavated in Mexico, and which he had studied while in Chicago. The large sculpture of Quetzlcoatl, hidden lights and the reddish hue contributed to the ambience of exoticism and mystery.

By 1928, his study under Lorado Taft ended as he was beginning to find that Taft academic style as well as the study of the casts of prominent Renaissance sculptures at the studio in Chicago did not suit him. After a long trip to Europe with Lorado Taft, he returned home, visually sated, ready to take the next step in his artistic development.

Cowan period

In 1928, he had left Midland Studios and joined R. Guy Cowan in Rocky River, Ohio, a suburb of Cleveland, where he and his colleague, Viktor Schreckengost became the leading sculptors of the Cowan Pottery studio. Unlike his contemporaries at the Cowan Studio, who were primarily influenced by Viennese modern pottery, Wiener Werksttte, Waylande Gregory was much more influenced by the Cleveland School as well as by leading American bronze sculptor Paul Manship who had also worked for Cowan.

Cowan studio works are generally table-top-sized sculptures done in limited editions. His most famous sculptures from this period are Europa, Nautch Dancer, and Burlesque, as well as Salome and Margarita. Salome combines the essential horror of the story of John the Baptist, his beheading, as well as Salome veil dance. However, the horror of the event is muted, becoming secondary to an expression of the line, movement and dynamics of the drapery and human movement. Salome won first prize at the Cleveland Museum of Art May Show of 1929. His Cowan work is characterized by smooth, linear, flowing forms.

In 1930 he married his wife Yolanda, a Hungarian immigrant. Their relationship appeared to evolve to be based more on friendship than sexual love. Although she could be very critical, she was always very supportive of him as an artist. Due to the onset of the Great Depression, Cowan Studios closed their doors in 1931, bringing this chapter of Waylande Gregory career to a close.

Cranbrook period

In 1931, Waylande Gregory became artist in residence at the Cranbrook Academy at Bloomfield Hills in Michigan, a suburb of Detroit. Here he was able to further develop his craft as, for the first time, he had access to the precise control of an electric kiln. His sculpture evolved into more Italianate forms, with more volume and weight than prior. Also, it was here he began to develop his sense of color more thoroughly, commenting that the hinese loved everything vivid and rich in tone, but we as a nation are just beginning to grow up to it. One of his most notable pieces is the terracotta sculpture of the Two Clowns on Unicycles, a complex piece of two clowns back-to-back, one playing a tuba, the other juggling poodles. The sculpture is vividly colored, unlike much American sculpture of the time, which was monochrome bronze. Other notable sculptures from this period are Ichabod Crane and the Kansas Madonna. In 1933, this period came to a close after a row with the manager of the Cranbrook Academy. The kilns had been shut down over a banker holiday, ruining many of his works in progress.

New Jersey period

In 1933, he and his wife Yolanda had moved to Perth Amboy where he had set up a workshop in the Atlantic Terra Cotta Company. This is where he developed his technique for the creation of monumental ceramic works utilizing an internal honeycomb-like structure, building the statue from the inside outward. As director of the New Jersey WPA, he began work on the monumental Light Dispelling Darkness which still stands in Roosevelt Park in Edison, New Jersey. Some photos are included in this article on the recently restored fountain. Others have been published in an article in Weird New Jersey.

Light Dispelling Darkness

Light Dispelling Darkness laid much of the technical groundwork for The Fountain of the Atom. It exhibits a heroic theme of combating evil through knowledge. It is a terracotta globe surrounding a shaft of relief figures of a scientist, artist, engineer, and muscular, un-shirted men apparently representing industrial workers or working-class people. On the outside are six figures representing conquest, war, famine, death, greed and materialism fleeing the forces of science and knowledge, an appropriate theme for Edison, NJ. Out of the six figures, 4 of them contain the horses of the Apocalypse.

Fountain of the Atoms

The Fountain of the Atoms was made for the 1939 World Fair. It is composed of the four elements, earth, air, fire and water, surrounded by eight electrons, 4 male and 4 female, similar to amorini. He described the electrons as, lemental little savages of boundless electrical energy, dancing to the rhythm of sculptured bolts of lightning-like flashes in brilliant colored glazes, their buoyant shaped bodies of richly modeled terracotta clays in warm colors. The four elements were grouped around illuminated tubes of glass which were topped by a flame, and carried water at the top of the fountain. Pictures of the maquette for earth and one of the electrons have been published. The fountain of the atoms was paired with his sculptural tableau, American Imports and Exports.

Later years

Having achieved critical success and reached the peak of his artistic powers in the 1930s, Waylande Gregory receded from the spotlight of publicity in later years. Conflict with his main art-gallery dealer and poor decisions regarding the pricing of his art, caused the popularity of his major works to decline. He began to make limited-edition works for large department stores such as Hammacher Schlemmer. One of the most famous of these is the table setting with dishes and centerpieces done on a theme of polo players, a favorite subject which he liked to watch at Schley Field in Far Hills. In 1942, he filed for a patent for his process of fusing glass to ceramic. In the remaining years, he would make money by teaching art classes, and made regular appearances on the television show, Ding Dong School. Things began to look up in the 1960s as he had acquired a patron in the form of Barbara Farmer who had begun arrangements to build a new arts center in Middlefield, Massachusetts. The hopeful prospects came to an abrupt end when she was murdered by her husband who suspected her of conducting an affair with Gregory. He returned to New Jersey to resume his work, but he was never the same after that incident.

As he became older, he began to have problems handling the heavy weight of ceramic for his monumental sculpture and began to branch out into hammered metal and lightweight materials such as foam, intended for later rendering in ceramic. His hammered lead sculpture The Dreamer won a silver medal from the National Sculpture Society in 1970.

Pertex is a versatile, wind resistant, durable wicking fabric with more breathing ability than waterproof membranes. It is typically found in down jackets and sleeping bags. water distillers

The breathability of Pertex comes from the fabrics use of capillary action using denier gradients. Pertex combines two yarns with different properties. The inner yarn has larger filaments and outer yarn has smaller filaments. Capillary action moves moisture from larger filaments to smaller filaments without passing through the air. water distiller

Imagine a bundle of very fine fibres next to an equal weight bundle of thicker fibres. The same weight of material can make more thin fibres than an equal amount of thick fibres, thus there are more thin fibres on the outer side (and a tighter weave) than there are thick fibres on the inside. The bundle of finer fibres has greater surface over which moisture can spread - so they will evaporate moisture more quickly. The moisture from the inside is directed to the thinner fibres from thicker fibres by, again, capillary action. The driving force behind all this is the temperature difference between your own body heat on the inside and the air temperature on the outside.

Pertex is windproof because of the tight weave of the outer surface. The breathing ability of the fabric is not based on air passing through the weave of the fabric, but by moisture absorbed in the inner yarn passed to the outer yarn (which passes from the outer yarn to the outside air). Adding a waterproof coating would trap the moisture in the yarn, instead of letting it pass through the yarn and evaporate into the air.

Fire fighting foam

China Suppliers


Class A foams

Class A foams were developed in mid 1980s for fighting wildfires. Class A foams lower the surface tension of the water which assists in the wetting and saturation of Class A fuels with water. This aids fire suppression and can prevent reignition. Favorable experiences led to its acceptance for fighting other types of class A fires, including structure fires.[dead link] cd duplicator

Class B foams dvcam tape

Class B foams are designed for class B fires - flammable liquids. The use of class A foam on a class B fire may yield unexpected results, as class A foams are not designed to contain the explosive vapors produced by flammable liquids. Class B foams have two major subtypes. duplication dvd replication

Synthetic foams

Synthetic foams are based on synthetic surfactants. Synthetic foams provide better flow, faster knockdown of flames, but limited post-fire security.

Aqueous film forming foams (AFFF) are water-based and frequently contain hydrocarbon-based surfactant such as sodium alkyl sulfate, and fluorosurfactantuch as fluorotelomers, perfluorooctanoic acid (PFOA), or perfluorooctanesulfonic acid (PFOS). They have the ability to spread over the surface of hydrocarbon-based liquids. Alcohol-resistant aqueous film forming foams (AR-AFFF) are foams resistant to the action of alcohols, able to form a protective film when they are present.

Protein foams

Protein foams contain natural proteins as the foaming agents. Unlike other synthetic foams, protein foams are bio-degradable. They flow and spread slower, but provide a foam blanket that is more heat resistant and more durable.

Protein foams include regular protein foam (P), fluoroprotein foam (FP), alcohol resistant fluoroprotein foam (AR-FP), film forming fluoroprotein (FFFP), and alcohol-resistant film forming fluoroprotein (AR-FFFP).

Protein Foam from non-animal sources is preferred because of the possible threats of biological contaminants like prions.

Applications

Every type of foam has its application. High-expansion foams are used when an enclosed space, such as a basement or hangar, needs to be quickly filled. Low-expansion foams are used on burning spills. AFFF is best for spills of jet fuels, FFFP is better for cases where the burning fuel can form deeper pools, AR-AFFFF is suitable for burning alcohols. The most flexibility is achieved by AR-AFFF or AR-FFFP. AR-AFFF must be used in areas where gasolines are blended with oxygenates, since the alcohols prevent the formation of the film between the FFFP foam and the gasoline, breaking down the foam, rendering the FFFP foam virtually useless.

History of Fire Fighting Foams

Water has long been a universal agent for suppressing fires, but is not best in all cases. For example, water is typically ineffective on an oil fire, and can be dangerous. Fire fighting foams were a positive development in extinguishing oil fires.

In the late 1800s, a method of extinguishing flammable liquid fires by blanketing them with foam was introduced. The original foam was a mixture of two powders and water produced in a foam generator. It was called chemical foam because of the chemical action to create it. Generally, the powders used were sodium bicarbonate and aluminium sulfate, with small amounts of saponin or liquorice added to stabilise the bubbles. Hand-held foam extinguishers used the same two chemicals in solution: to actuate the extinguisher, a seal was broken and the unit inverted, allowing the liquids to mix and react. Chemical foam is a stable solution of small bubbles containing carbon dioxide with lower density than oil or water, and exhibits persistence for covering flat surfaces. Because it lighter than the burning liquid, it flows freely over the liquid surface and extinguishes the fire by a smothering action. Chemical foam is considered obsolete today because of the many containers of powder required, even for small fires.

In the 1940s Percy Lavon Julian developed an improved type of foam called Aerofoam. Using mechanical action, a liquid protein-based concentrate, made from soy protein, was mixed with water in either a proportioner or an aerating nozzle to form air bubbles with the free flowing action. Its expansion ratio and ease of handling made it popular. Protein foam is easily contaminated by some flammable liquids, so care should be used so that the foam is only applied above the burning liquid. Protein foam has slow knockdown characteristics, but it is economical for post fire security.

In the 1960s National Foam, Inc. developed fluoroprotein foam. Its active agent is a fluorinated surfactant which provides an oil-rejecting property to prevent contamination. It is generally better than protein foam because its longer blanket life provides better safety when entry is required for rescue. Fluoroprotein foam has fast knockdown characteristics and it can also be used together with dry chemicals which destroy protein foam...

In the mid 1960s the US Navy developed aqueous film-forming foam (AFFF) . This synthetic foam has a low viscosity and spreads rapidly across the surface of most hydrocarbon fuels. A water film forms beneath the foam which cools the liquid fuel, which stops the formation of flammable vapors. This provides dramatic fire knockdown, an important factor in crash rescue fire fighting.

In the early 1970s National Foam, Inc. invented Alcohol Resistant AFFF technology. AR-AFFF is a synthetic foam developed for both hydrocarbon and polar solvent materials. Polar solvents are combustible liquids that destroy conventional fire fighting foam. These solvents extract the water contained in the foam, breaking down the foam blanket. Therefore, these fuels require an alcohol or polar solvent resistant foam. Alcohol resistant foam must be bounced off of a surface and allowed to flow down and over the liquid to form its membrane, compared to standard AFFF that can be sprayed directly onto the fire.
