Libbey Incorporated
Libbey, Inc., (formerly Libbey Glass Company and New England Glass Company) is a glass production company headquartered in Toledo, Ohio. It was originally founded in 1818 in Cambridge, Massachusetts, as the ''New England Glass Company,'' before relocating to Ohio in 1888 and renaming to ''Libbey Glass Co''. After it was purchased in 1935, it operated as part of the Libbey-Owens-Ford company and as a division of the Owens-Illinois glass company until 1993, when it was separated back into an independent company. The company manufactures a number of glassware products, primarily tableware, drinkware and stemware. Historically, it was also involved in producing other types of glass products, such as automotive glass, glass drinking bottles, and light bulbs. History New England Glass Company (1818–1892) The New England Glass Company was originally founded in Cambridge, Massachusetts, by Amos Binney, Edmund Munroe, Daniel Hastings, and Deming Jarves on February 16, 1818.

Public Company
A public company is a company whose ownership is organized via shares of share capital, stock which are intended to be freely traded on a stock exchange or in over-the-counter (finance), over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listing (finance), listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states and so have associations and formal designations, which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation, though a corporation need not be a public company. In the United Kin ...

Glass Engraving
Engraved glass is a type of decorated glass that involves shallowly engraving the surface of a glass object, either by holding it against a rotating wheel, or manipulating a "diamond point" in the style of an engraving burin. It is a subgroup of glass art, which refers to all artistic glass, much of it made by "hot" techniques such as moulding and blowing melting glass, and with other "cold" techniques such as glass etching which uses acidic, caustic, or abrasive substances to achieve artistic effects, and cut glass, which is cut with an abrasive wheel, but more deeply than in engraved glass, where the engraving normally only cuts deeply enough into the surface to leave a mark. Usually the engraved surface is left "frosted" so a difference is visible, while in cut glass the cut surface is polished to restore transparency. Some pieces may combine two or more techniques. There are several different techniques of glass engraving. It has been practised since ancient times, including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soda-lime Glass
Soda lime, a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO), is used in granular form within recirculating breathing environments like general anesthesia and its breathing circuit, submarines, rebreathers, and hyperbaric chambers and underwater habitats. Its purpose is to eliminate carbon dioxide () from breathing gases, preventing carbon dioxide retention and, eventually, carbon dioxide poisoning. The creation of soda lime involves treating slaked lime with a concentrated sodium hydroxide solution. Chemical components The primary components of soda lime include: calcium oxide (CaO) constituting approximately 75%, water () accounting for around 20%, sodium hydroxide (NaOH) making up about 3%, and potassium hydroxide (KOH) present at approximately 0.1%. Anaesthesia During general anaesthesia, a patient's exhaled gases, containing carbon dioxide, pass through an anaesthesia machine's breathing circuit, containing a soda lime canister filled with soda lime granule ...

American Civil War
The American Civil War (April 12, 1861May 26, 1865; also known by Names of the American Civil War, other names) was a civil war in the United States between the Union (American Civil War), Union ("the North") and the Confederate States of America, Confederacy ("the South"), which was formed in 1861 by U.S. state, states that had Secession in the United States, seceded from the Union. The Origins of the American Civil War, central conflict leading to war was a dispute over whether Slavery in the United States, slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction. Timeline of events leading to the American Civil War, Decades of controversy over slavery came to a head when Abraham Lincoln, who opposed slavery's expansion, won the 1860 presidential election. Seven Southern slave states responded to Lincoln's victory by seceding f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paperweight
A paperweight is a small solid object heavy enough, when placed on top of papers, to keep them from blowing away in a breeze or from moving under the strokes of a painting brush (as with Chinese calligraphy). While any object, such as a stone, can serve as a paperweight, decorative paperweights of metal, glass, jade or other material are also produced, either by individual artisans or factories. In the West, the decorative paperweights are usually in limited editions, and are collected as works of fine glass art, some of which are also exhibited in museums. First produced in about 1845, particularly in France, such decorative paperweights declined in popularity before undergoing a revival in the mid-twentieth century. Basic features Decorative glass paperweights have a flat or slightly concave base, usually polished but sometimes frosted, cut in one of several variations (e.g. star-cut bases have a multi-pointed star, while a diamond cut base has grooves cut in a criss-cros ...

Pressed Glass
Pressed glass (or pattern glass) is a form of glass made by pressing molten glass into a Molding (process), mold using a plunger. Although hand pressed glass has existed for over 1,000 years, the use of a machine for pressing was first patented by Pittsburgh glass man Bakewell Glass, John P. Bakewell in 1825 to make knobs for furniture. The technique was developed in the United States from the 1820s and in Europe, particularly France, Bohemia, and Sweden from the 1830s. By the mid-19th century, most inexpensive mass-produced glassware was pressed (1850–1910). One type of pressed glass is carnival glass. Painted pressed glass produced in the early 20th century is often called goofus glass. The method is also used to make beads. See also * Millefiori References |
Franklin Institute
The Franklin Institute is a science museum and a center of science education and research in Philadelphia, Pennsylvania. It is named after the American scientist and wikt:statesman, statesman Benjamin Franklin. It houses the Benjamin Franklin National Memorial. Founded in 1824, the Franklin Institute is one of the oldest centers of science education and development in the United States. Its chief astronomer is Derrick Pitts. History 19th century On February 5, 1824, Samuel Vaughan Merrick and William H. Keating founded the Franklin Institute of the State of Pennsylvania for the Promotion of the Artes Mechanicae, Mechanic Arts. The opening was chronicled by ''The Literary Chronicle for the Year 1824'': Begun in 1825, the institute was an important force in the professionalization of American science and technology through the nineteenth century, beginning with early investigations into steam engines and water power. In addition to conducting scientific inquiry, it fostered re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Institute Fair
The American Institute Fair was held annually from 1829 until at least 1897 in New York City by the American Institute. The American Institute was founded in 1829 "for the encouragement of agriculture, commerce, manufactures, and the arts." The fair is sometimes considered the first world's fair in the United States The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic of 50 U.S. state, states and a federal capital district, Washington, D.C. The 48 ..., though it was fairly small by later standards, drawing about 30,000 attendees per year.

Crown Glass (window)
Crown glass was an early type of window glass. In this process, glass was blown into a "crown" or hollow globe. This was then transferred from the blowpipe to a punty and then flattened by reheating and spinning out the bowl-shaped piece of glass (bullion) into a flat disk by centrifugal force, up to 5 or 6 feet (1.5 to 1.8 metres) in diameter. The glass was then cut to the size required. The thinnest glass was in a band at the edge of the disk, with the glass becoming thicker and more opaque toward the center. Known as a bullseye, the thicker center area around the pontil mark was used for less expensive windows. To fill large window spaces with the best glass, many small diamond shapes were cut from the edge of the disk, and then some might be halved into triangles. These were mounted in a lead lattice work and fitted into the window frame. Crown glass was one of the two most common processes for making window glass until the 19th century. The other was blown plate. Crown ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flint Glass
Flint glass is optical glass that has relatively high refractive index and low Abbe number (high dispersion). Flint glasses are arbitrarily defined as having an Abbe number of 50 to 55 or less. The currently known flint glasses have refractive indices ranging between 1.45 and 2.00. Traditionally, flint glasses were lead glasses containing around 4–60% lead(II) oxide; however, the manufacture and disposal of these glasses were sources of pollution. In many modern flint glasses, lead oxides are replaced with other metal oxides such as titanium dioxide and zirconium dioxide without significantly altering the optical properties of the glass. Applications A concave lens of flint glass is commonly combined with a convex lens of crown glass to produce an achromatic doublet lens because of their compensating optical properties, which reduces chromatic aberration (colour defects). History With respect to glass, the term ''flint'' derives from the flint nodules found in the ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
