Black zero-expansion glass-ceramic is primarily used in cooking

appliances—induction cooker, infrared cooker and tea brewers

—as well as heating units in vehicles like RVs. Our LEAD black                                     

glass-ceramic panel delivers exceptional heat resistance up to 

820°C, meeting the heat requirement of all cook styles, 

from Middle Eastern grilling to high-heat Chinese cooking.

Through continuous formula optimization, we've minimized lateral thermal conductivity to near-zero—reducing safety risks from prolonged heat transfer and preventing damage to electrical components.

It supports virtually all specialty surface treatments and offers impressive impact resistance.
