Extra High-Temperature Easy-Machine Glass-Mica Ceramic Sheets and Bars

Also known as Macor, this glass-mica ceramic withstands temperatures up to 1470° F. You can machine complicated shapes and precision parts from it in a fraction of the time it would take using other types of fired ceramic. Its good electrical and thermal resistance make it a common choice for heating and soldering fixtures.
