Pewter Medal
Pewter () is a malleable metal alloy consisting of tin (85–99%), antimony (approximately 5–10%), copper (2%), bismuth, and sometimes silver. In the past, it was an alloy of tin and lead, but most modern pewter, in order to prevent lead poisoning, is not made with lead. Pewter has a low melting point, around , depending on the exact mixture of metals. The word ''pewter'' is possibly a variation of "spelter", a term for zinc alloys (originally a colloquial name for zinc). History Pewter was first used around the beginning of the Bronze Age in the Near East. The earliest known piece of pewter was found in an Egyptian tomb, , but it is unlikely that this was the first use of the material. Pewter was used for decorative metal items and tableware in ancient times by the Egyptians and later the Romans, and came into extensive use in Europe from the Middle Ages

Porcelain
Porcelain (), also called china, is a ceramic material made by heating Industrial mineral, raw materials, generally including kaolinite, in a kiln to temperatures between . The greater strength and translucence of porcelain, relative to other types of pottery, arise mainly from Vitrification#Ceramics, vitrification and the formation of the mineral mullite within the body at these high temperatures. End applications include tableware, ceramic art, decorative ware such as figurines, and products in technology and industry such as Insulator (electricity), electrical insulators and laboratory ware. The manufacturing process used for porcelain is similar to that used for earthenware and stoneware, the two other main types of pottery, although it can be more challenging to produce. It has usually been regarded as the most prestigious type of pottery due to its delicacy, strength, and high degree of whiteness. It is frequently both glazed and decorated. Though definitions vary, po ...

Singapore
Singapore, officially the Republic of Singapore, is an island country and city-state in Southeast Asia. The country's territory comprises one main island, 63 satellite islands and islets, and one outlying islet. It is about one degree of latitude () north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south along with the Riau Islands in Indonesia, the South China Sea to the east, and the Straits of Johor along with the State of Johor in Malaysia to the north. In its early history, Singapore was a maritime emporium known as '' Temasek''; subsequently, it was part of a major constituent part of several successive thalassocratic empires. Its contemporary era began in 1819, when Stamford Raffles established Singapore as an entrepôt trading post of the British Empire. In 1867, Singapore came under the direct control of Britain as part of the Straits Settlements. During World ...

Lead Poisoning
Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility, numbness and paresthesia, tingling in the hands and feet. It causes almost 10% of intellectual disability of otherwise unknown cause and can result in behavioral problems. Some of the effects are permanent. In severe cases, anemia, seizures, coma, or death may occur. Exposure to lead can occur by contaminated air, water, dust, food, or consumer products. Lead poisoning poses a significantly increased risk to children and pets as they are far more likely to ingest lead indirectly by chewing on toys or other objects that are coated in lead paint. Additionally, children absorb greater quantities of lead from ingested sources than adults. Exposure at work is a common cause of lead poisoning in adults with certain occupations at particular risk. Diagnosis is typically b ...

Redox
Redox ( , , reduction–oxidation or oxidation–reduction) is a type of chemical reaction in which the oxidation states of the reactants change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. The oxidation and reduction processes occur simultaneously in the chemical reaction. There are two classes of redox reactions: * Electron transfer, Electron-transfer – Only one (usually) electron flows from the atom, ion, or molecule being oxidized to the atom, ion, or molecule that is reduced. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * Atom transfer – An atom transfers from one Substrate (chemistry), substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously, the oxidation state of oxygen decreases as it accepts electrons r ...

United States Figure Skating Championships
The U.S. Figure Skating Championships are an annual figure skating competition organized by U.S. Figure Skating to crown the national champions of the United States. The first U.S. Championships were held in 1914 in New Haven, Connecticut, and featured the men's, women's, and pairs events. They have been held without interruption since 1920. Ice dance was added as an event in 1936. Skaters may qualify for the national championships by competing at either the Pacific Coast Sectional Finals, Eastern Sectional Finals, Midwestern Sectional Finals, U.S. Ice Dance Finals, or U.S. Pairs Finals. Medals are awarded in men's singles, women's singles, pair skating, and ice dance at the senior and junior levels. The results of the competition are among the criteria used to determine the American teams to the World Championships, World Junior Championships, Four Continents Championships, and Winter Olympics. Roger Turner currently holds the record for winning the most U.S. cha ...

Electroplating
Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the redox, reduction of cations of that metal by means of a direct current, direct electric current. The part to be coated acts as the cathode (negative electrode) of an electrolytic cell; the electrolyte is a solution (chemistry), solution of a salt (chemistry), salt whose cation is the metal to be coated, and the anode (positive electrode) is usually either a block of that metal, or of some inert electrical conductor, conductive material. The current is provided by an external power supply. Electroplating is widely used in industry and decorative arts to improve the surface qualities of objects—such as resistance to abrasion (mechanical), abrasion and corrosion, lubrication, lubricity, reflectivity, electrical conductivity, or appearance. It is used to build up thickness on undersized or worn-out parts and to manufacture metal ...

Beer Stein
A beer stein ( ), or simply stein, is either a traditional beer mug made out of stoneware or specifically an ornamental beer mug sold as a souvenir or collectible. An 1894 article on beer mugs in the American Vogue (magazine), ''Vogue'' magazine that describes various types of steins stated: "And it is to this [i.e. German] nation that we owe Richard Wagner, Wagner's music and the apotheosis of the beer mug." Such steins may be made out of stoneware, pewter, porcelain or even silver, wood or crystal glass; they may have open tops or hinged pewter lids with a thumb-lever. Steins usually come in sizes of a half litre or a full litre (or comparable historic sizes). Like decorative tankards, they are often decorated in a nostalgic manner with allusions to Germany. Etymology The English word is attested from 1855. It is borrowed from German language, German ', which has – aside from its prevailing meaning "stone" – elder regional meanings "beer mug" and "beer measure of 1 litre ...

Porringer
A porringer is a shallow bowl, between 100 and 150 mm (4–6 inches) in diameter, and 38 to 76 mm (–3 inches) deep; the form originated in the medieval period in Europe and was made in wood, ceramic, pewter, cast iron and silver. They had flat, horizontal handles. The precise purpose of porringers, or écuelles, as they are known in France, is in dispute; but it is thought that they were used to hold broth or gruel. Colonial porringers tended to have one handle, whereas European ones tended to have two handles on opposite sides, on which the owner's initials were sometimes engraved, and they occasionally came with a lid. Porringers resembled the smaller quaich, a Scottish drinking vessel. One can discern authentic pewter porringers in much the same way that silver can be authenticated from the touch marks that were stamped either into the bowl of the porringer or on its base. Wooden porringers are occasionally found from excavations, e.g., 16th-century example from Southwa ...
