Tea kettles with an open spout are whistling tea kettles though some tea kettles intentionally place some additional spout covering or contraption which emits a different whistling sound. Buying a whisling kettle may seem like a task requiring little consideration, but bearing in mind that your kettle may be the most used item in your kitchen so please pay a proper attention in choosing the right one.
The whistling sound of a tea kettle depends on the size of the opening of the spout and its neck length. In the process of heating water in a kettle, as the water heats, some of it turns into vapor and this vapor must somehow exit or escape from the pot. As the vapor makes its way to the spout, it produces a hissing sound as it moves from one temperature to another. This hissing sound may vary depending on the structure of the spout. Some spouts have covers which can alter the sound of the vapor. Once the vapor exits the spout, it is transformed into steam. Thus you see a bit of that steam and a lot of that hiss in the kettle. That is how the whistling tea kettle got its name.
Some hisses were actually made accidentally as some spouts were misshaped by accident perhaps during travel. Some spouts were actually bent into having a smaller aperture. This was very common during the 1800′s in North America especially during the Great Land Drive when homesteaders were given land in what used to be Native American territory. Nowadays, there are many types of whistling tea kettles to choose from and they come with a variety of price ranges.
These are only few of the whistling tea kettles available in the physical stores or online. Depending on the design that you want, the longer the neck of the kettle, the louder its whistle.
