batu kali. Wine glass is a non-crystalline amorphous stable that is often translucent and has wide-spread practical, technical, and decorative consumption in, for example, windowpane panes, tableware, and optoelectronics. The best familiar, and historically the oldest, types of wine glass are "silicate spectacles" predicated on the chemical mixture silica (silicon dioxide, or quartz), the principal constituent of fine sand. The term a glass, in popular use, is often used to send only to this kind of materials, which is familiar from use as screen a glass and in wine glass bottles. Of the numerous silica-based glasses which exist, normal glazing and box glass is developed from a particular type called soda-lime wine 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, providing rise with their major use as screen panes. Goblet will transmit, echo and refract light; these features can be increased by trimming and polishing to make optical lens, prisms, fine glassware, and optical fibres for broadband data transmitting by light. Goblet can be colored with the addition of metallic salts, and can even be painted and printed out with vitreous enamels. These features have resulted in the comprehensive use of wine glass in the make of art items and specifically, stained glass glass windows. Although brittle, silicate goblet is incredibly durable, and many types of glass fragments can be found from early on glass-making ethnicities. Because a glass can be produced or moulded into any form, it's been typically used for vessels: bowls, vases, containers, jars and drinking alcohol eyeglasses. In its most stable forms it has additionally been used for paperweights, marbles, and beads. When extruded as wine glass fiber content and matted as wine glass wool in ways to capture air, it becomes a thermal insulating materials, so when these glass fibres are inlayed into an organic and natural polymer plastic, they are simply an integral structural reinforcement area of the composite materials fiberglass. Some items historically were so commonly manufactured from silicate glass they are simply called by the name of the materials, such as drinking alcohol spectacles and reading eyeglasses.

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 level and that displays a glass changeover when heated on the liquid talk about. Porcelains and many polymer thermoplastics familiar from day-to-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 a glass containers or eyewear, polymer eyeglasses (acrylic a glass, polycarbonate or polyethylene terephthalate) are a lighter solution than traditional wine glass.
