Glass Ceramic Uses
How we use glass and glass ceramics.
Glass ceramic uses. Kitchenware based on pyrex glass is ovenproof and used to cook premium baked goods. For restoration and renovation glass craftsman plays an important role. Thus the glass ceramic mgo al 2 o 3 sio 2 is used to make electrical insulators that have to operate at high temperatures such as spark plug insulators. Ceramics are also used at many places in gas turbine engines.
Bio ceramics are used as dental implants and synthetic bones. Ceramics and glass are beneficial in the kitchen for cooking storing and serving food. For ornamental work glass is available in wide ranges of texture colours finishes and shapes. Even in our modern age of plentiful plastics brick glass cement concrete porcelain and tiles of all kinds are still the raw materials from which most buildings are made.
Glass ceramics are also stronger at high temperatures than glasses. To convert them from a vitreous glass material into a crystalline glass ceramic material they must be heat treated or devitrified. Devitrification can occur spontaneously during cooling or in service but is most commonly incorporated to. As a result they are used to make pottery bricks tiles cements and glass.
The properties and uses of some glasses and glass ceramics are given in the table below. Due to the method of heat transfer used in most glass top stoves stoneware will simply fail. Also all extra heavy cookware pieces should be avoided including stoneware. Traditionally and logically windows are the great canvas of glass art.
Noncrystalline ceramics being glass tend to be formed from melts. Ceramic forming techniques include shaping by hand sometimes including a rotation process called throwing slip casting tape casting used for making very thin ceramic capacitors injection molding dry pressing and other variations. In particular you should generally avoid glass or ceramic cookware sets because they tend to leave marks behind on the glass and may melt onto the glass if left unattended. With the use of glass architects maintain a deliberate balance between coloured light and airy space.
Wineglasses pitchers and jars are obtained from blown glass. Soda lime glass for example is one standard. The finest tableware and cookware are made from porcelain. A glass ceramic stove uses radiant heating coils or infrared halogen lamps as the heating elements.
The surface of the glass ceramic cooktop above the burner heats up but the adjacent surface remains cool because of the low heat conduction coefficient of the material. Glass ceramic components are formed using the same processes that are applicable to glass components. The diversity of glass formulations and the sophisticated material and process know how of glass experts present many options. Ceramic products are hard porous and brittle.
Designers and product engineers select glass and glass ceramics possessing properties that meet the needs of their product or project.
