A new window will open and you'll be able to get yourself a real bargain.Cordierite is a magnesium iron aluminium cyclosilicate. Iron is almost always present and a solid solution exists between Mg-rich cordierite and Fe-rich sekaninaite with a series formula: (Mg,Fe)2Al4Si5O18 to (Fe,Mg)2Al4Si5O18. A high temperature polymorph exists, indialite, which is isostructural with beryl and has a random distribution of Al in the (AlSi)6O18 rings. Cordierite ceramic is commonly used in catalytic converters. Cordierite is named after the French geologist P. L. A. Cordier (1777 - 1861). Cordierite typically occurs in contact or regional metamorphism of argillaceous rocks. It is especially common in hornfels produced by contact metamorphism of pelitic rocks. Courtesy of Wikipedia
