Glass kettles: pros, cons and the COSORI 1.5L 3000W

Glass kettles: pros, cons and the COSORI 1.5L 3000W

A glass kettle turns an everyday job into something to look at, glowing blue as it boils. But is glass practical? Here's an honest look, with the COSORI 1.5L glass kettle as an example.

At a glance

  • 3000 W: about 43 seconds for one cup, according to COSORI
  • 1.5 litre capacity, up to 6 cups
  • Glass body with a blue light while boiling
  • 304 stainless steel inner lid and filter, with a glass V-shaped spout
  • Lid opens to two levels to reduce splashing
  • Strix boil control with auto shut-off and boil-dry protection

Pros of a glass kettle

  • You can see exactly how much water is inside, so it's easy to boil only what you need.
  • Limescale is easy to spot, so you know when to descale.
  • It looks good on the worktop, especially when lit.

Things to bear in mind

  • Scale shows up more clearly, so it needs descaling often in hard water areas.
  • Glass gets hot. Hold it only by the handle.
  • Handle it with care to avoid knocks.

How to keep a glass kettle sparkling

  1. Half-fill with equal parts water and white vinegar, or use a kettle descaler.
  2. Boil, then leave it for about an hour.
  3. Pour away, rinse, then boil and discard fresh water once or twice.
  4. Wipe the outside with a soft cloth once cool.

Always check the manual before descaling.

Frequently asked questions

Is 1.5 litres enough?

It's up to six cups, which suits most homes. It also takes up a little less space than a 1.7 litre kettle.

What is Strix boil control?

Strix is a well-known maker of kettle controls. It switches the kettle off when the water boils and protects it if switched on empty.
