Glass is made of sandstone.  Stone would be earth.

No....glass is considered an amorphic substance. In other words, its structure looks the same in all directions from within the material.

Zinc is by far the best element. I also like plutonium.  It's just fun to say. "Plutonium."

Mercury and Bromine are the only liquids in the Periodic table. Francium, cesium, gallium, and rubidium are four elements that melt at temperatures slightly higher than room temperature.

It was actually manganese and not magnesium that was used in antique glassware.  A combination of manganese and UV rays results in the color change that is now too often seen in many antique pieces. \n\nAround 1860, most American glass companies used manganese in their glass formulas.  By 1915, most companies had stopped using manganese and replaced it with selenium.

Glass consists of a mixture of silicates, barates or phosphates that cools to a rigid condition without crystallization. (It can be made of quartz-sand, lime, soda, potash and lead oxide.) Crystal falls into the 3 main categories. Fine Crystal or Crystalline is made from a glass mixture that contains 6% - 10% lead oxide. Lead Crystal is made from a glass mixture that contains 10% - 24% lead oxide and Full Lead Crystal is made from a glass mixture that contains 24% lead oxide or more. For the most part, crystal by European standards regards 24% lead bearing glass as crystal. However, by American standards, any glass that is perfectly clear is considered crystal regardless of the lead content. Lead oxide in crystal gives the product clarity and sparkle. Any crystal that is hand-cut usually must be 24% lead oxide or over - otherwise the crystal would be too brittle and would break when cut or engraved.

Be windows are used because, Be is the lowest atomic number solid. Since Be only has an atomic number of 3, it has low absorption or reflection of a detection beam (presumably electrons or other atomic particle).

There are different types of glass, with different specific heat values.  Specific Heat is also called Heat Capacity.\n\nFlint Glass   0.503 Joules / gram Kelvin\nPyrex Glass   0.753 Joules / gram Kelvin

Magnesium is the 12th element (atomic number 12).\n\nCarbon is the 6th element, but has an atomic mass of 12.

Solid, there are only 2 elements that are liquid at room temperature, Mercury, and Bromine. 2 other elements will melt from the heat of your hand, (slightly above room temperature), Cesium and Gallium.

All all of them bend, stretch and break. But glass has a very low capacity for bending, it is microscopical. Metal stretches, but it has a very low capacity and so on.

Emeralds are Beryl, which has a hardness of 7.5 to 8 and can certainly scratch glass. Glass is silica, with a hardness of 6 to 7.\nDiamond, the hardest of all substances, gets the big 10. \nBeryl has been found in about every color of the rainbow, but green is most common.

Facts about the definition of the element silicon:\nThe Element Silicon is defined as...\nA non-metallic element occurring extensively in the earth's crust in silica and silicates, having both an amorphous and a crystalline allotrope, and used doped or in combination with other materials in glass, semi-conducting devices, concrete, brick, refractories, pottery, and silicones.\n\nInteresting facts about the origin and meaning of the element name silicon:\nWhat are the origins of the word Silicon ?\nThe name originates from the Latin word 'silex' meaning flint or hard stone. The high-tech region of Silicon Valley, California, is named after this element.\n\nFacts about the Classification of the Element Silicon:\nSilicon is classified as a "Metalloid" element and is located in Groups 13, 14,15, 16 and 17 of the Periodic Table. An element classified as a Metalloid has properties of both metals and non-metals. Some are semi-conductors and can carry an electrical charge making them useful in calculators and computers.\n\nBrief facts about the discovery and history of the element silicon:\nSilicon was first identified by Antoine Lavoisier in 1787. Re-discovered by Jons Berzelius in 1823\n\nOccurrence of the element silicon:\nOccurring extensively in the earth's crust in silica and silicates\nElemental silicon is not found in nature\nSilicon is a principal component of aerolites and of tektites\n \nCommon uses of silicon:\nSemi-conductors\nGlass\nConcrete\nBrick\nPottery\nSilicones\n \nThe properties of the element silicon:\nName of Element : Silicon\nSymbol of Element : Si\nAtomic Number of Silicon : 14\nAtomic Mass: 28.0855 amu\nMelting Point: 1410.0ºC - 1683.15ºK\nBoiling Point: 2355.0ºC - 2628.15ºK\nNumber of Protons/Electrons in Silicon : 14\nNumber of Neutrons in Silicon : 14\nCrystal Structure: Cubic\nDensity @ 293 K: 2.329 g/cm3\nColor of Silicon : gray\n\nProperties\n\n\nThe melting point of silicon is 1410ºC, boiling point is 2355ºC, specific gravity is 2.33 (25ºC), with a valence of 4. Crystalline silicon has a metallic grayish color. Silicon is relatively inert, but it is attacked by dilute alkali and by halogens. Silicon transmits over 95% of all infrared wavelengths (1.3-6.7 mm).\n\nUses\n\nSilicon is one of the most widely used elements. Silicon is important to plant and animal life. Diatoms extract silica from water to build their cell walls. Silica is found in plant ashes and in the human skeleton. Silicon is an important ingredient in steel. Silicon carbide is an important abrasive and is used in lasers to produce coherent light at 456.0 nm. Silicon doped with gallium, arsenic, boron, etc. is used to produce transistors, solar cells, rectifiers, and other important solid-state electronic devices. Silicones range from liquids to hard solids and have many useful properties, including use as adhesives, sealants, and insulators. Sand and clay are used to make building materials. Silica is used to make glass, which has many useful mechanical, electrical, optical, and thermal properties.\n\nSources\n\nSilicon makes up 25.7% of the earth's crust, by weight, making it the second most abundant element (exceeded by oxygen). Silicon is found in the sun and stars. It is a principal component of the class of meteorites known as aerolites. Silicon is also a component of tektites, a natural glass of uncertain origin. Silicon is not found free in nature. It commonly occurs as the oxide and silicates, including sand, quartz, amethyst, agate, flint, jasper, opal, and citrine. Silicate minerals include granite, hornblende, feldspar, mica, clay, and asbestos.\n\nPreparation\n\nSilicon may be prepared by heating silica and carbon in an electric furnace, using carbon electrodes. Amorphous silicon may be prepared as a brown powder, which can then be melted or vaporized. The Czochralski process is used to produce single crystals of silicon for solid-state and semiconductor devices. Hyperpure silicon may

A crystal shape is the arrangement of the molecules in a compound...carbon fiber is a crystalline structure since it is arranged in a pattern when observed under a microscope. Glass, however isn't a crystalline structure, and will be disorganized. Also, a quick fact is that glass will always be in motion due to it's non-crystalline structure. The bottom of a pane of glass will be thicker than the top after many years :) A high melting point means that it will take more heat to induce a state change... Metal is frozen at room temperature and has a high melting point, as opposed to water, which has a melting point around 33 degrees farenheit.
