Tiffany Glass
Tiffany glass refers to the many and varied types of glass developed and produced from 1878 to 1933 at the Tiffany Studios in New York City, by Louis Comfort Tiffany and a team of other designers, including Clara Driscoll, Agnes F. Northrop, and Frederick Wilson. In 1865, Tiffany traveled to Europe, and in London he visited the Victoria and Albert Museum, whose extensive collection of Roman and Syrian glass made a deep impression on him. He admired the coloration of medieval glass and was convinced that the quality of contemporary glass could be improved upon. In his own words, the "Rich tones are due in part to the use of pot metal full of impurities, and in part to the uneven thickness of the glass, but still more because the glass maker of that day abstained from the use of paint". Tiffany was an interior designer, and in 1878 his interest turned toward the creation of stained glass, when he opened his own studio and glass foundry because he was unable to find the types of ...

Girl With Cherry Blossoms - Tiffany Glass & Decorating Company, C
A girl is a young female human, usually a child or an adolescent. When a girl becomes an adult, she is accurately described as a ''woman''. However, the term ''girl'' is also used for other meanings, including ''young woman'',Dictionary.com, "Girl"'' Retrieved January 2, 2008. and is sometimes used as a synonym for ''daughter'', or ''girlfriend''. In certain contexts, the usage of ''girl'' for a woman may be derogatory. ''Girl'' may also be a term of endearment used by an adult, usually a woman, to designate adult female friends. ''Girl'' also appears in portmanteaus (compound words) like ''showgirl'', ''cowgirl'', and '' schoolgirl''. The treatment and status of girls in any society is usually closely related to the status of women in that culture. In cultures where women have a low societal position, girls may be unwanted by their parents, and the state may invest less in services for girls. Girls' upbringing ranges from being relatively the same as that of boys to comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Nitrate
Silver nitrate is an inorganic compound with chemical formula . It is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides. It was once called ''lunar caustic'' because silver was called ''luna'' by ancient alchemists who associated silver with the moon. In solid silver nitrate, the silver ions are three- coordinated in a trigonal planar arrangement. Synthesis and structure Albertus Magnus, in the 13th century, documented the ability of nitric acid to separate gold and silver by dissolving the silver. Indeed silver nitrate can be prepared by dissolving silver in nitric acid followed by evaporation of the solution. The stoichiometry of the reaction depends upon the concentration of nitric acid used. :3 Ag + 4 HNO3 (cold and diluted) → 3 AgNO3 + 2 H2O + NO :Ag + 2 HNO3 (hot and concentrated) → AgNO3 + H2O + NO2 The structure of silver nitrate has been examined by X-ray crystallography sever ...

Iridescence
Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear to gradually change color as the angle of view or the angle of illumination changes. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and minerals such as opal. It is a kind of structural coloration that is due to wave interference of light in microstructures or thin films. Pearlescence is a related effect where some or most of the reflected light is white. The term pearlescent is used to describe certain paint finishes, usually in the automotive industry, which actually produce iridescent effects. Etymology The word ''iridescence'' is derived in part from the Greek word ἶρις ''îris'' ( gen. ἴριδος ''íridos''), meaning ''rainbow'', and is combined with the Latin suffix ''-escent'', meaning "having a tendency toward". Iris in turn derives from the goddess Iris of Greek mythology, who is the personification of the rainbow and ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...
