Keep your brew warmer for longer
Tea appears to magically float inside this sleek, ergonomic glass. The illusion is down to its innovative design – a highly effective double layer of insulation that keeps hot and cold drinks at the desired temperature for longer.
Crafted from strong, ultra-light, heat-resistant borosilicate glass, our Double Walled Glass Mug can be used to serve all hot and cold brews – from your favourite loose-leaf teas, to coffee, beer and iced drinks. Thanks to the mug’s thermal resistance, you can comfortably hold the cup no matter what temperature the liquid inside is.
Because this glass is mouth-blown, each one may have slight differences in height, thickness and weight. We invite you to enjoy the uniqueness of this lovely, handmade product. Delivered in a smart The Tea Makers of London presentation box, it also makes a beautiful gift for a friend.
Materials
Strong borosilicate glass.
More luxury glass teaware
Keep it glassy and pair this piece with one of our elegant teapots, also made from heat-resistant borosilicate glass.
Caring for your borosilicate glass mug
Borosilicate glass is made mainly of silica (70-80%) and boric oxide (7-13%), with smaller amounts of alkalis (sodium and potassium oxides) and aluminium oxide. Used in cookware and chemistry labs, it’s renowned for its resistance to thermal shock. However, as a glass product, a certain amount of care still needs to be taken:
• Please be careful when placing ice into the glass mug and when using metal spoons to avoid fracturing the inner layer. We suggest first pouring in the liquid, followed by the ice.
• If the ambient temperature in the kitchen is low, warming up the mug before use will help it last longer. The glass is less likely to break or shatter if you warm it up gradually. Once you have poured in the hot tea, avoid resting the mug on cold surfaces.
• Please note that you will find a small air-hole at the bottom of the glass. This is not a flaw but a safety measure, put in place to control the air pressure between the walls. Simply rinse with hot water and avoid using the dishwasher. Clean the bottom gently with a soft sponge and avoid putting pressure on the hole. Avoid brushing, otherwise water may become trapped inside the opening and fog up between the two walls.
