Why Use Double-Walled Mugs?

Double-walled mugs are as much a practical kitchen addition as they are a decorative one.

Once you’re aware of the benefits of these nifty vessels you might never go back to the humble ceramic mug.

Whether you’re a latte lover or espresso evangelist, we have an extensive range of pretty, double-walled mugs that not only look great in your kitchen but also extend your drink’s life span.

What is a double-walled mug?

 

As the name suggests, these stylish mugs consist of a double layer of material – usually borosilicate glass. Borosilicate glass contains boron trioxide and has a low coefficient of thermal expansion.

This means that, unlike regular glass, it doesn’t crack under extreme heat and can cope with temperatures up to 100 degrees. 

The double layer of glass makes them thicker, but not necessarily heavier. Borosilicate glass is in fact a naturally light-weight material.

These pretty mugs are essentially a glass within a glass. In between the layers is a pocket of air and since air has a lower thermal conductivity than glass, heat cannot pass easily between the layers. Heat is retained for longer, and your drink stays warm. It’s the perfect vessel, then, for a piping hot cuppa.

What are the benefits of double-walled mugs?

 

  • Heat retention

 

First and foremost, the insulating properties of the double-walled mug is its greatest benefit.

There’s nothing more frustrating than forgetting about your cup of coffee and returning to find it tepid.

 

There’s less chance of this happening with a layered mug.

The pocket of air between the glass keeps your drink hotter for hours longer than in a regular mug.

 

  • Keep things chilled

 

The insulation works in reverse too. Unlike regular glass, heat can neither escape, nor enter easily, so your chilled iced tea will remain refreshing for far longer on a hot summer’s day.

 

  • Prevent scolded hands

 

Because the extra layer of glass blocks the inside heat from escaping too quickly, it also stops the outside of the mug from becoming too hot to the touch.

Passing a cuppa between friends has never been easier. 

 

  • Clear

 

Why does it matter that your cup’s transparent? Well, it means you can see exactly how much tea you have left and whether or not it’s time for a top-up!

 

  • Chic and stylish

There’s a reason cool coffee houses and high-end eateries use double-walled mugs. Aside from all the above benefits, they also look elegant.

How to care for your double-walled mug

 

Please be aware that Pretty Little Home’s double-walled mugs are not dishwasher safe. To ensure the longevity of your favourite mug, ensure you hand wash only by doing the following:

 

  • Fill the inside of the mug with warm, soapy water
  • Wash clean with a cloth or brush
  • Rinse with hot running water

 

*Do not submerge the mug for long periods as this encourages water to seep through seams.
