No, glass utensils cannot be used directly on an induction cooktop. Induction cooktops work by creating an electromagnetic field that interacts with ferromagnetic materials (materials that contain iron or have magnetic properties). When you place a compatible pot or pan made from ferromagnetic materials on the induction cooktop, the magnetic field induces electrical currents within the cookware, generating heat and cooking the food.
Glass, unfortunately, is not a ferromagnetic material and, therefore, cannot be directly heated by an induction cooktop. If you try to place a glass utensil on an induction cooktop, it will not heat up or cook your food.
To use an induction cooktop, you need cookware made from materials that are compatible with induction heating. Examples of suitable materials include cast iron, stainless steel (with a magnetic base), enameled cast iron, and some types of induction-ready cookware with multiple layers of magnetic metals.
Always check the cookware's label or packaging to see if it is specifically labeled as "induction-compatible" before using it on an induction cooktop. Using the right cookware ensures efficient cooking and helps prevent damage to both the cookware and the induction cooktop.
