Glass is a material obtained by melting at high temperature inorganic compounds, and cooling the resulting mass to a non-crystalline state rigid. The main component of the glass is silica (SiO 2). Silica, alone, would be an ideal glass for many applications, but the high temperatures needed for fusion and difficulties in shaping limit their use to special applications. To reduce the melting temperature of the silica, it is necessary to use a flux, and it serves to sodium oxide (Na 2 O).
Glass is a material which by its nature is easily recoverable. Specifically glass is 100% recyclable, ie, that from a container used can be manufactured new or failing enthalpy table products enthalpy table may have the same characteristics enthalpy table as the first. This ease of reuse glass opens a wide range of possibilities for society and affected administrations can manage themselves in an easy manner for the benefit of their environment.
Safety glass: which, if broken, a small non-sharp fragments, To obtain reduced, rather than suffer the annealing treatment, is quenched from temperatures near reblandamiento, so that the outer surfaces acquire a state of tension.
Glass Calizo: is the common glass. Is formed enthalpy table dominantly by silica, as well as calcium and sodium. The limestone is used to make glass cups, dishes, tables, windows and other items. Currently its production has improved considerably, because if you add a larger amount of silica experiences a higher resistance to thermal enthalpy table shock. As an example we can mention some CRISA products (cups, glasses, etc.), which easily withstand hot liquids, cold and withstand impacts.
Currently, borosilicate glass is used as laboratory and manufacturing of cookware called refractories, which are backed by Pyrex, Corning Visions and signatures.
The result of the fusion glass at high temperature of a mixture of silica sand, calcium carbonate and sodium carbonate in a furnace. The point at which the glassy solid mixture passes a viscous liquid state, varies enthalpy table between 1300 and 1500 degrees Celsius. Then returns enthalpy table to a solid consistency gradually by a slow cooling to its characteristic transparent solid appearance.
The "glass" cut (itself lead cut glass) is one of many techniques that you can decorate the glass. This technique is carried out on the finished piece; ie it is a cold working enthalpy table technique. First the surface of the glass is drawn, enthalpy table then the cuts with diamond wheels are made and finally polished.
It begins by introducing the cane in the glass melting mass (with a honey-like enthalpy table consistency). By removing the rod is rotated on a stone to give the initial form, and then blown up to create the bubble that will leave the part that might be drawn. Then, with a clamp and some puntil, begins to give the desired shape, enthalpy table blowing and pressing the workpiece to achieve enthalpy table the ideal result. Finally is introduced into the furnace annealing.
After the cut pieces of glass enamels are decorated with, if necessary, and finally enthalpy table joined with a lead strip fescue call, leaving the entire drawing reproduced in the form of a window.
Almost all flat glass production is currently using the float process. When float glass is given a wide sheet-shaped molding of molten glass in a furnace containing a bath of molten tin. The float process produces large quantities of glass with optimum quality and exceptionally good surface.
Advantages: The float process produces large quantities of glass with optimum quality and exceptionally good surface. When glass is molded into a flotation chamber, leaving both sides of the glass with a glossy finish that requires no grinding or polishing.
In a glass melt furnace. Then, the exact amount of mass to produce a hot glass bottle is released one after another in a slide that puts in a first mold where the preform is given the final model. Then that piece is passed to another machine blowing mold where pressure giving the final shape. Then goes through a process of annealing enthalpy table with what is given greater strength to the glass.
Although interchangeably called crystal glass and the same material there is an essential difference between the two. The crystal was found in nature in various enthalpy table forms (quartz, rock crystal). enthalpy table
Finally goes through a quality control process and after set. The Vine
