What is the material of the Glass kettle heating element? Is it concealed or exposed?

Glass electric kettles typically have heating elements made of stainless steel or other metal alloys. These heating elements are typically concealed within the base of the kettle, beneath the glass body. The concealed heating element design offers several benefits:
Safety: Concealed heating elements are less exposed, reducing the risk of accidental burns or contact with hot surfaces.
Ease of Cleaning: With the heating element concealed, there are no exposed coils or heating elements to clean around, making the kettle easier to clean and maintain.
Durability: By being shielded from direct contact with water and other elements, concealed heating elements may last longer and be less susceptible to corrosion or damage.
Aesthetics: Concealed heating elements contribute to a sleek and streamlined appearance, enhancing the overall aesthetic appeal of the kettle, especially in the case of glass kettles where the heating element is visible through the transparent body.
concealed heating elements are a common design feature in glass electric kettles, providing safety, ease of cleaning, durability, and aesthetic benefits.
