How to care for your glassesClose
Caring For Your Borosilicate Glass Cups
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 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 glasses before use will help the glasses 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 glass on cold surfaces.
• To clean your Shell Double Walled Glass Cups, we advise rinsing with hot water and avoiding the dishwasher. It will help keep them pristine and avoid scuff marks. Clean the outside gently with a soft sponge and do not apply pressure on the air hole at the bottom.
