Dolomite: A sedimentary rock known as dolostone or ...Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg (CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesiumrich groundwater. Dolomite and limestone are very similar rocks.
What is Dolomite ceramic? · Dolomite as a ceramic material is a uniform calcium magnesium carbonate. ... Ceramic ware is glazed before entering a kiln to bake. ... Vitrified China is vitrified during the single firing process at about 1200 °C in the kiln and is more durable than dolomite.
DolomiteDolomite is a carbonate (like whiting) in that it loses considerable weight during firing when it disassociates to form MgO, CaO and CO 2, this process being complete by about 900C. In many circumstances where a raw glaze employs both CaO and MgO, dolomite is an economic alternative to sourcing with a mix of calcium carbonate and talc.
