So, you saw Rochelle Humes sipping away at her matcha latte inthosecups again and couldn't resist getting your hands on a pair?
Yep, it turns out the Saturdays beauty opts for a double-walled drinking cup that keeps your drink of choice hot OR cold for longer - pretty cool, right?
How do glass coffee cups work?
They may look cool but, let's be honest, this is the question on all of our minds.
Double-walled thermo cups work by using a vacuum between the outer and inner layers of glass. By having a vacuum (no air) in this gap, it essentially means that neither heat nor cold can escape through the glass. Of course, your coffee or tea will still cool/warm over time, but these cups slow the process.
Now that you're clued up on the tech side, let's get down to aesthetics. You can get glass coffee mugs in loads of styles, from cute bear-shaped ones (perfect for kids) to minimalist tempered glass coffee cups and saucers, there's plenty to choose from.
Lucky for you, we've filtered through all the best ones so you don't have to. So, whether you're a sucker for crockery with character, or you'd rather buy all your homeware in a nice uniform style - we've got the picks for you.

Are glass coffee mugs microwave safe?
In short, it will depend on the type of glass.
According to Samsung, while ceramic and ovenproof glass are indeed microwave safe, ordinary non-tempered glass will crack with exposure to the excessive heat.
Generally speaking, if the glass is durable enough to withstand boiling water, then it should be safe to use in the microwave, but you should always check the manufacturer instructions.
