gelas kaca

gelas kaca. A glass is a non-crystalline amorphous sturdy that is often clear and has wide-spread practical, scientific, and decorative use in, for example, home window panes, tableware, and optoelectronics. Essentially the most familiar, and historically the oldest, types of a glass are "silicate spectacles" predicated on the chemical element silica (silicon dioxide, or quartz), the principal constituent of fine sand. The term goblet, in popular consumption, is often used to send only to this kind of materials, which is familiar from use as screen goblet and in goblet bottles. Of the numerous silica-based glasses which exist, common glazing and pot glass is developed from a particular type called soda-lime a glass, composed of about 75% silicon dioxide (SiO2), sodium oxide (Na2O) from sodium carbonate (Na2CO3), calcium mineral oxide, also known as lime (CaO), and many minor additives.

Many applications of silicate spectacles are based on their optical transparency, offering rise with their principal use as windows panes. Cup will transmit, indicate and refract light; these attributes can be increased by lowering and polishing to make optical lens, prisms, fine glassware, and optical materials for broadband data transmitting by light. Wine glass can be colored with the addition of metallic salts, and can even be painted and imprinted with vitreous enamels. These characteristics have resulted in the comprehensive use of goblet in the make of art items and specifically, stained glass home windows. Although brittle, silicate goblet is incredibly durable, and many types of glass fragments can be found from early on glass-making civilizations. Because goblet can be developed or moulded into any form, it's been customarily used for vessels: bowls, vases, containers, jars and taking in spectacles. In its most sound forms it has additionally been used for paperweights, marbles, and beads. When extruded as a glass dietary fiber and matted as wine glass wool in ways to capture air, it becomes a thermal insulating materials, so when these glass fibres are inserted into an organic and natural polymer plastic, they can be an integral structural reinforcement area of the composite materials fiberglass. Some things historically were so commonly manufactured from silicate glass they are simply called by the name of the materials, such as drinking alcohol eyeglasses and reading spectacles.

Scientifically, the word "glass" is often identified in a broader sense, encompassing every sound that possesses a non-crystalline (that is, amorphous) framework at the atomic size and that displays a glass change when heated for the liquid express. Porcelains and many polymer thermoplastics familiar from each day use are eyeglasses. These kinds of glasses can be produced of quite different sorts of materials than silica: metallic alloys, ionic melts, aqueous alternatives, molecular fluids, and polymers. For most applications, like goblet containers or eyewear, polymer spectacles (acrylic goblet, polycarbonate or polyethylene terephthalate) are a lighter substitute than traditional goblet.
