Induction cooking device

An induction cooking device, comprising:

• an inductor;
• and
• a thermally strengthened glass plate,
• wherein a glass of the glass plate is a lithium aluminosilicate comprising at least one of TiO2 and ZrO2, wherein at least one of TiO2 and ZrO2 is present and a combined content of TiO2 and ZrO2 is at least 2% by weight based on a total weight of the glass,
• wherein the chemical composition of the glass comprises silica SiO2 in a weight content ranging from 49% to 75%, alumina Al2O3 in a weight content ranging from 15% to 30%, lithium oxide Li2O in a weight content ranging from 1% to 8%, and Na2O in a weight content ranging from 0% to 3%, all weights based on the total weight of the glass,
• wherein the inductor is positioned under the glass plate,
• wherein the device is suitable for operation at 390° C.,
• wherein the glass plate does not break when the device operates at 390° C. to boil 200 mL of water and for 15 minutes afterward, and
• the device does not comprise a Si3N4 coating deposited on the glass plate.
