Muscovite Mineral | Uses and Properties
The ability of muscovite to split into thin transparent sheets - sometimes up to several feet across - gave it an early use as window panes. In the 1700s it was mined for this use from pegmatites in the area around Moscow, Russia. These panes were called "muscovy glass" and that term is thought to have inspired the mineral name "muscovite."

Thermodynamics of the kaolinite-group minerals
The enthalpies of formation of kaolinite and dickite were determined by high-temperature melt solution calorimetry to be ΔfH°(298.15 K) = −4118 ± 10 and −4127 ±10 kJ/mol, respectively. These data represent the first calorimetric confirmation of the metastability of kaolinite with respect to dickite.
