What Makes a Tea Kettle Induction Compatible?
If you are looking for a new tea kettle and have an induction cooker at home, keep in mind that induction hobs are not compatible with every tea kettle. Induction stoves have many advantages but require cooking vessels that are optimized for induction cooktops.
To use a tea kettle on an induction stove, two main requirements must be met:
1. The base must be made of magnetic material: Kettles suitable for induction are made of magnetic stainless steel, enameled steel, or have a multi-layer base with a ferromagnetic layer. Magnetic materials attract the magnet and support the magnetic field that heats the water in the kettle.
Tea kettles made of glass, ceramic, aluminum, or copper tea kettles will not work with induction cooktops unless they have a layer of magnetic metal on the bottom.
2. Appropriate bottom diameter and shape: The base of the tea kettle should fit the induction cooking zone. A smaller base diameter than the cooking surface results in slower heating of the water.
The bottom must also be completely flat and smooth so that it rests on the cooking surface without interruption. An uneven bottom results in slow heating and the kettle can vibrate and make more noise than it normally would.
How to Know if Your Tea Kettle is Induction-Ready
To find out if your tea kettle is optimized for induction cooking, read the product description. Another option is to look for an induction compatibility symbol at the bottom or a note on the packaging. Finally, you can perform a magnet test by holding a magnet to the bottom. If the magnet sticks to the bottom, your tea kettle is suitable for induction.

Stainless Steel Tea Kettles
Not all stainless steel kettles are induction-compatible. Stainless steel is an alloy of several metals. Some metals, such as nickel, can block the magnetic field when present in high concentrations. So you can use any of the above methods to make sure it works on an induction stove.
Stainless steel tea kettles are popular with many tea lovers due to their attractive modern look that fits most kitchen décor. They are also durable and compatible with all heat sources.
A potential disadvantage of stainless steel is its poor thermal conductivity. For this reason, high-quality quality tea kettles have a base made of a combination of steel and aluminum, with the aluminum core sandwiched between layers of steel. Such a multi-clad kettle is suitable for induction and can save energy and time.
Stainless steel tea kettles are dishwasher safe but can also be easily cleaned by hand. All you need to do is rinse your kettle after each use to prepare it for the next brewing session.

Are Cast Iron Tea Kettles Suitable for Induction?
Most cast iron tea kettles on the market are extremely attractive and can give your kitchen an antique look. Most of these decorative kettles have an enamel lining on the inside to make maintenance easier.
Cast iron kettles could theoretically work on an induction stove because iron is a magnetic material. However, there are two reasons why it is not recommended to use cast iron teapots on an induction stove:
1. Cast iron pieces are very heavy and can damage the glass surface if not handled carefully.
2. The bottom of the cast-iron kettle is not smooth enough to fully adhere to the glass surface. Any warping of the bottom causes the magnetic field to drop. There is also an increased risk of the glass being scratched when you move the kettle. If you decide to use a cast iron kettle on an induction stove, it is important to place it carefully on the glass and avoid sliding.
Although cast iron doesn’t spread the heat quickly and evenly cast-iron kettles can be a good choice for standard gas or electric cooktops. However, if you want to take good care of your induction cooktop, a cast-iron kettle is not the best choice.
Enamel Tea Kettles
Enamel tea kettles have a carbon steel core with a porcelain or ceramic coating. They are suitable for use on almost all heat sources (except gas stoves), including induction stoves. The smooth kettle base nestles completely against the cooking surface of your induction hob.
Enamel tea kettles look very attractive and stylish. They are available in different colors, with classic and modern shapes, and are beautifully designed. An enamel kettle adds bright colors to your kitchen.
Enamel tea kettles are corrosion-resistant and do not form mineral deposits. To protect the integrity of the enamel surface, do not put it in the dishwasher. Hand washing is recommended and is very easy.
An additional advantage of enamel-coated tea kettles is that the enamel interior is inert and there is no possibility of heavy metals leaching into the boiling water as long as the interior enamel coating is undamaged.

Tea Kettles with Encapsulated Bottom
The induction kettles can be more efficient and energy-saving than regular kettles, but encapsulated base tea kettles go even further.
The base of these tea kettles is multi-layered. It contains ferromagnetic metal on the outside of the base, while the interior is made of an inert material, usually stainless steel that does not leach into hot water and does not alter the taste. The aluminum or copper core is sandwiched between layers of stainless steel to maximize heat conduction and reduce heat-up time. Magnetic stainless steel ensures compatibility with induction hobs. A three-layer base also helps maintain the temperature of water or tea for longer.
