The soda reduces the sand's melting point, which helps to save energy during manufacture, but it has an unfortunate drawback: it produces a kind of glass that would dissolve in water! The limestone is added to stop that happening. The end-product is called soda-lime-silica glass. It's ...

Everyone has a basic familiarity with what is metalworking. Metalworking processes have been driving the world even before the earliest civilizations. In fact, eras of ancient times were named after metalworking processes they used, such as the Iron Age and Bronze Age. ...
Sintering of zirconia occurs well below its melting point. 4 Calcination Involves thermal decomposition. The calcination process thermally decomposes organic materials in ores. 3 Sintering A process used to create objects from powders. Sintering of iron ore fines is used to make stronger pellets. 3 ...
Oak (n.) Any tree or shrub of the genus Quercus. The oaks have alternate leaves, often variously lobed, and staminate flowers in catkins. The fruit is a smooth nut, called an acorn, which is more or less inclosed in a scaly involucre called the cup or cupule. There are now recogniz...
