Such is the story of an Arkansas man who drank so much iced tea that it led him to develop kidney failure. Three Arkansas doctors described the case in a letter published by the New England Journal of Medicine this week.
What is Marble? Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.
No two patterns of granite are the same. Each is a unique piece of art created by nature. It is antibacterial and can be highly polished, making it ideal for kitchens, entryways and bathrooms. How Is Granite Created? Where Does It Come From? Granite is hard igneous stone that is formed over millions of years by volcanic activity. Magma flows from volcanic activity and slowly cools over millions of years. During the process, magma combines with various minerals including hornblend, feldspar, mica and quartz to create its crystal appearance.
