A very important advance in glass manufacture was the technique of adding lead oxide to the molten glass; this improved the appearance of the glass and made it easier to melt using sea-coal as a furnace fuel. This technique also increased the "working period" of the glass, making it easier to manipulate.
In 1966, GE announced a ceramic "transparent as glass", called Yttralox. [12] In 2004, Anatoly Rosenflanz and colleagues at 3M used a "flame-spray" technique to alloy aluminium oxide (or alumina) with rare-earth metal oxides in order to produce high strength glass-ceramics with good optical properties. The method avoids many of the problems ...
In the visible range glass-ceramics can be transparent, translucent or opaque and even colored by coloring agents. However, glass-ceramic is not totally unbreakable. Because it is still a brittle material as glass and ceramics are, it can be broken – in particular it is less robust than traditional cooktops made of steel or cast iron.
After a short detour to Harvard for business school, Weeks came back to Corning in 1987 to develop a strategy for specialty glass and ceramics, studying science textbooks in his off hours to gain ...
Glass-ceramics exhibit advantageous thermal, chemical, biological, and dielectric properties as compared to metals or organic polymers. [87] The most commercially important property of glass-ceramics is their imperviousness to thermal shock. Thus, glass-ceramics have become extremely useful for countertop cooking and industrial processes.
Aluminium oxynitride is the hardest polycrystalline transparent ceramic available commercially. [ 2 ] [ needs update ] Because of its relatively low weight, distinctive optical and mechanical properties, and resistance to oxidation or radiation, it shows promise for applications such as bulletproof , blast-resistant, and optoelectronic windows ...
3-D printing is revolutionizing manufacturing, allowing anyone to make their own designs come to life and impressing us with incredible achievements.
This was the first glass-ceramic and eventually led to the development of CorningWare in 1957. CorningWare went to the consumer marketplace the next year in 1958 for cookware by Corning Glass Works and became just one of Stookey's multimillion-dollar inventions. It influenced the development of VisionWare, which is transparent cookware. [3]
