Copper is the material this kettle is made of, that's why it's named that way.

Stainless steel or heat-resistant plastic are common materials for kettle handles as they offer durability and heat resistance. The material should also provide a comfortable grip to safely handle the kettle when pouring hot liquids. Ultimately, the best material will depend on personal preference and the specific design of the kettle.
Most kettle heating elements are made of a metallic material, such as stainless steel or nickel-chromium alloy. These materials are chosen for their heat resistance, durability, and ability to efficiently transfer heat to the water.
Boiling. Just as cracking is a type of breaking, kettle is a type of device used for boiling water or other liquid.
To increase a kettle's efficiency, you can use a kettle that is the right size for your needs, regularly descale it to remove mineral buildup, and match the heat source to the kettle material. Additionally, keeping the kettle lid on while heating water and using an insulated kettle can help retain heat and improve efficiency.
A color changing kettle is typically made from temperature-sensitive material such as thermochromic paint or coating that changes color when heated. The material reacts to the change in temperature, resulting in a visual color transformation on the surface of the kettle.
The time it takes for a kettle to cool down can vary depending on the material of the kettle, the amount of water inside, and the surrounding temperature. On average, it may take anywhere between 30 minutes to an hour for a kettle to cool down completely.
Thermal energy is conducted through the walls of a kettle by the process of conduction. Within the walls of the kettle, the particles of the material vibrate and transfer energy to neighboring particles through direct contact. This transfer of kinetic energy continues throughout the material, allowing the heat to spread and warm the contents of the kettle.

Rust in a kettle is not necessarily dangerous to health, but it can affect the taste and quality of the water or food being prepared in it. It is recommended to avoid using a kettle with rust, as it may indicate deterioration of the material and potential contamination.
