For more information about its history, see the book "All That Glitters" (available at ) and micaclay. Data sheets for various mica products quote a wide range of decomposition and melting temperatures (as high as 1800C for melting and 1500C for decomposition). A typical melting point of muscovite is around 1250-1300C.
