• Pros: Stainless steel is known for its durability and ability to withstand everyday wear and tear. It won’t crack, chip, or break if accidentally dropped.

• Cons: Over time, stainless steel may develop scratches or lose its polished shine, but this does not affect its functionality.

Verdict: If durability is your top concern, a stainless steel kettle is the more robust option, capable of withstanding the rigors of daily use. However, if you handle your appliances carefully and prioritize style, a high-quality glass kettle can still be a long-lasting choice.

3. Safety

Safety is a crucial consideration when using any kitchen appliance, especially one that involves boiling water. Both glass and stainless steel kettles have safety features, but there are differences in the safety concerns associated with each material.

Glass Kettles: Non-Toxic and Chemical-Free

One of the main advantages of glass kettles is that they are non-toxic and free from harmful chemicals. Glass does not leach chemicals into the water, even at high temperatures, making it a safe option for health-conscious users. There are no concerns about metallic taste or odors affecting the flavor of your boiled water.

• Pros: Glass is chemically inert, meaning it won’t interact with the water or release harmful substances. It is also a good choice for people who are concerned about plastic or metal contamination.

• Cons: Glass kettles are more likely to shatter or crack if dropped, so extra care is needed to handle them safely.

Stainless Steel Kettles: Safe and Sturdy

Stainless steel kettles are generally very safe to use, as they are highly resistant to damage and unlikely to break or shatter. However, some cheaper stainless steel kettles may impart a metallic taste to the water, especially if the steel is of lower quality. Additionally, some users may be concerned about the use of nickel or other metals in the kettle's construction, though high-quality stainless steel kettles are usually free of such concerns.

• Pros: Stainless steel kettles are sturdy, safe, and resistant to damage. They are less prone to shattering than glass kettles and are often equipped with safety features such as auto shut-off.
