What Type Of Materials Are The Safest For Tea Kettle?

To make a perfect and colorful cup of green tea without the bitterness, you have to brew it the right way. If you heat the water with a microwave, the water will overheat and exceed the boiling point due to radio waves, so superheat water will destroy the original flavor of the tea. Therefore, you need to use a tea kettle to brew teas properly.

You should distinguish different types of equipment for tea. Specifically, the teapot is only used to steep the tea, the tea kettle is used to brew tea directly on the stove. For tea kettle, there are various materials and this makes it difficult to choose a harmless material. In this article, we will point out the non-toxic materials for a tea kettle.

Keep reading and you will find the safest materials for a tea kettle.

Materials to avoid when choosing a non-toxic tea kettle

Tea kettle should not be made of aluminum

Aluminum tea kettle can percolate aluminum salt. Many cooking utensils can still be made of aluminum, but studies are showing that aluminum can lead to Alzheimer’s disease and may even affect the ability to absorb substances like calcium, magnesium, and iron of the organs in the body.

If lead and mercury have a direct and strong impact on our health, aluminum will often have a gradual impact over time. The human body can absorb aluminum at an acceptable level of about 3-5 mg per day without causing immediate adverse effects.

However, through experiments, scientists found that the amount of aluminum we consume daily is usually higher than 3-5mg if we use cookware made of aluminum.

Fortunately, the human body always has an excellent detoxifying function, so we do not completely absorb all the aluminum in food, but the aluminum residue is quickly excreted. However, there is no denying that aluminum has no harmful effects on our bodies.

Aluminum bioaccumulates in the human body. That means over time, aluminum will slowly build up in your body and lead to diseases related to this substance.

Therefore, you should avoid using tea kettle made from aluminum. When you use an aluminum tea kettle to brew tea several times a day, it will cause negative effects on your health.

Tea kettle should not be enameled

You should not use tea kettle but have an enamel coating because these enamels often have heavy metals and these toxic metals will seep into the tea water when you heat on the stove.

Lead is a typical metal found in cookware or dishes and it can also be found in tooth enamel. Like aluminum, lead has a biological accumulation, which is a gradual buildup over time.

As you know, lead causes negative health effects such as osteoarthritis, impairment of internal organs and the most common disease are cancer. Therefore, when choosing a non-toxic tea boiler, you must avoid the one that contains lead in the glaze.

However, the question is how do you know whether tea kettle has lead or not. Fortunately, a scientist named Tamara Rubin conducted experiments on cooking utensils with enamel coating including various items such as ceramic mugs, enamel tea kettle, enameled ovens, etc. The result of that experiment was lead or even cadmium found in all of these objects.

For this reason, we recommend that you do not buy tea kettle with enamel coating. If you still want to buy an enameled tea kettle, consider and make sure the product is labeled with the California Prop 65 warning, a Toxic Enforcement Act.

The Office of Environmental Health Hazard Assessment, operated by California Proposition 65, points out two levels of lead limits in cookware that affect human health. Lead becomes carcinogenic when higher than 15 micrograms and is reproductive toxicity when it is at a maximum of 0.5 micrograms.

Harmless materials for your best tea kettle

The material of tea kettle that you should choose to buy is stainless steel (unornamented) and plain glass (unornamented). These materials have the advantage of being toxic-free and cheap. All tea boilers made from stainless steel or glass are safe no matter what country it is made in, even China.

Stainless steel tea kettle

Tea kettle made of stainless steel is usually brighter and more beautiful charcoal aluminum. The advantage of stainless steel is that the heat distribution is good, the heat radiates evenly to the cookware components and responds well to heat changes.

In contrast, cast iron retains heat very well, so if tea kettle is made from cast iron, it also helps the tea to heat longer but that makes it difficult to adjust the appropriate water temperature to brew the tea.

Tamara Rubin also conducted some tests on cookware made of stainless steel and confirmed that the material does not contain lead, cadmium or arsenic.

However, the disadvantage of stainless steel is that it leaches nickel during thermal impact. Stainless steel also leaks chromium and iron into food, which is good for the body. However, nickel is not a nutrient our bodies need to absorb. This is probably the only drawback of stainless steel.

Therefore, when comparing between stainless steel and other materials such as aluminum and ceramic, the scientists concluded that stainless steel is the best material that is strongly advised for cookware, specifically tea kettle.

Another advantage of a stainless steel tea kettle is that the boiling water used for tea does not cause nickel filtration. The reason is that you usually pour boiling water right into the tea after water boiled in the tea kettle, so the time that boiling water stored in a tea kettle is shorter.

Additionally, purified water is usually not as acidic as other types of water such as soup, so the nickel filtration rate of the stainless steel tea kettle is very low.

Glass tea kettle

The biggest advantage of non-crystal glass is that it does not filter nickel, lead or cadmium into the water. Modern glass such as heat-resistant glass and tempered glass does not contain lead, cadmium, arsenic or mercury, according to Tamara Rubin’s experiment.

You should choose clear, colorless glass as this is the type that does not contain toxic substances. If the glass is light blue or blue, this is recycled glass, which is positive for lead, so it is harmful to human health.

Although recycled glass is good for the environment, it should be avoided for cookware. Consequently, you should choose lead-free tea kettle to ensure your health.


In this article, we have just shown you the pros and cons of each material for making tea kettle. We strongly advise using stainless steel or lead-free glass tea kettles to ensure they do not contain heavy metals and contaminants, helping to protect your health.
