Intelligent british design 


There's a reason the Glowstone heated smart mug maintains the perfect drinking temperature for your hot drink, time and time again. We're proud to only ever build reliable, durable and exceptionally high-quality products and our mug's consistent delivery and finish is a testament to our ongoing commitment to quality. 




Perfect drinking temperature, for longer. 


Experiments show the optimum drinking temperature for tea and coffee is 60°C to 65°C. Our patented Glowstone Core Technology waits for your drink to reach this perfect drinking temperature and automatically maintains such perfection for an extra hour, in 2 half hour heat cycles.

The world's first self-heating china mug.

It’s not a flask or a cup with a lid. It’s a mug that exudes quality, craftsmanship and understated class. It’s the first of its kind and every inch of its design has been considered to ensure the optimum drinking conditions without imposing on your tea and coffee drinking experience. Weighing the same as other mugs, the effortless simplicity of this mug lets you feel every moment and savour every sip.

Saying something is smart shouldn’t make it complicated. Glowstone have proven this by creating an intelligent mug without the headache.

Fine bone china improves taste. 

In 1799, Josiah Spode II invented bone china. He discovered that by mixing bone ashes with clay. It could be fired at a lower temperature than porcelain but maintain its durability and delicate look. The end result is a brilliant white, translucent, delicate but extremely strong piece of ceramic.

We believe fine bone china shouldn’t just be for special occasions. The thinness of bone china lets your drink cool down to the perfect temperature quicker, and the glass glazing process enhances the delicate flavours and aromas of your hot drink.

It would have been easy for us to use stainless steel or plastic as most vacuum flasks do but this taints the flavour, and we never compromise on taste.

Scientifically engineered to the last drop.

There’s real science to creating a mug that delivers perfect tea and coffee, and we’ve spent two years developing the perfect solution. 

Research proves tea and coffee taste better at 60°C to 65°C, and fine bone china is proven to deliver better tasting tea and coffee. Glowstone’s smart mug effortlessly delivers the optimum drinking temperature, optimum taste, and optimum delivery for your tea and coffee right down to the last sip.

The mug that delivers more.

Glowstone’s heated smart mug was born out of frustration, as most great inventions usually are.


Nowadays, with the latest innovations in home drinks making machines, it’s possible for everyone to make lovingly brewed tea and coffee at home. The problem is that while the technology is improving, no one is thinking about the actual delivery of the drink. Even with the most advanced drinks making machines, your drink will only stay at the perfect drinking temperature for a few minutes. It was this discovery that made us realise a good hot drink should remain at the perfect temperature until the last sip, and this shouldn’t mean compromising on taste or mug quality.

Through months of countless experiments and designs, we finally found a way to deliver and maintain the perfect drinking temperature of 60°C to 65°C for an extra hour*, time and time again.

By combining the finest bone china with our patented Glowstone Core Technology, we’ve found a way to deliver not only the perfect temperature drink but also the perfect taste. Give it a try. You’ll never look back.


We're on a mission to optimise everyday products to make life more enjoyable.


Wireless charging

The Glowstone mug comes with a stylish Qi coaster. The coaster comes with a standard micro USB lead and plug power adaptor, and can be operated from any USB socket such as those found on your laptop or computer. As a bonus, the coaster can also be used to recharge other home devices such as smartphones and tablets.

Dishwasher Safe

The Glowstone mug can be treated like any other mug. As the electronics are completely sealed in the base, it's fully dishwasher proof. And, just in case you were wondering, the mug knows when it's upside down so will not accidentally turn on when it's in the dishwasher.

Automatic switch off at last sip 

The Glowstone mug is designed to switch off when you take your last sip. You'll see the light go off as you drink the last drop. And if you don't finish your drink within the hour, it'll turn off automatically anyway. 

Holds your drink at the perfect temperature 

It is widely accepted that tea and coffee should be consumed between 60-65 degrees and in a fine china mug to appreciate their flavours fully. The Glowstone mug will keep your drink at this temperature right down to the last drop.

Mug's base remains cool while keeping your drink hot  

The mug's base remains cool while keeping your drink at the perfect temperature so that it won't damage any of your delicate surfaces.
