Vitreous enamel - Wikipedia, the free encyclopedia (750 words) |
 | In a discussion of art or technology, enamel (or vitreous enamel, or porcelain enamel in American English) is the colorful result of fusion of powdered glass to a substrate through the process of firing, usually between 750 and 850 degrees Celsius. |
| The durability of enamel has given it many functional applications, including: early 20th century advertising signs, interior walls of ovens, speckleware cooking pots, exterior walls of high quality kitchen appliances, cast iron bathtubs, storage silos on farms and process equipment such as chemical reactors and tanks for the chemical and pharmaceutical process industries. |
| Color in enamel is obtained by the addition of various minerals, often metal oxides cobalt, praseodymium, iron, or neodymium. |
| Enamel Developement (1297 words) |
| The process by which enamel proteins such as amelogenin mediate the formation of hydroxyapatite crystals from calcium and phosphate is called enamel biomineralization. |
| Enamel crystals are some of the most astounding structures in nature featuring extremely long and parallel organized hydroxyapatite crystals organized in bundles which are called prisms. |
| Tooth enamel is a wonderful biomineral that evolves as the result of highly controlled interactions between specialized enamel proteins and tooth minerals. |
