Size
Checking the height of your glass coffee cup is vital before you make any purchases, as the size of a drinking utensil can sometimes render them incompatible with certain coffee machines.
In general, a traditional mug tends to not stretch much further than 10 cm in height and so if your coffee machine’s spout rests anywhere below that, you may have trouble squeezing it into place!
Price
The prices in glassware tend to vary quite wildly and you need to consider why some items might be more expensive than others. Pay too little and you’re likely to end up with a poor quality glass product.
Set Size
There’s rarely any point in buying just one single glass, even if you live alone. Because then how are you meant to serve any guests that come round? Personally, we would suggest single mugs to be bought as gifts, or at most just a personal treat for yourself.
Otherwise, it’s smarter to get sets of between 2 and 4, so your family and friends can always be catered for, as well as yourself!
Design
From personal engravings to pretty hand painted patterns, no one says your glass coffee mug has to be a disappointingly plain and clear cup. Try and find something which reflects your personal style or that matches the decor or other tableware in your house!
Other Features To Look For
Borosilicate Material
Borosilicate glass is made through combining the chemical components of silica and boron trioxide in the creation process. This makes it the most heat-resistant form of glass available, ensuring easier handling and longer lasting coffees.
Double-Walled Thermal Insulation
Double-walled glasses provide two layers of glass in their structure, with a pocket of air between the outer layer you hold and the inner layer which contains your drink. As well as appearing more visually exciting, it also improves the mug’s insulation and is thicker and sturdier in shape so can present cracking and shattering more easily.
Microwave & Dishwasher Safe
Being able to easily clean a drinking utensil which has the potential to become rife with coffee stains is incredibly important if you want your item to have any sort of longevity and maintain it’s crystal clear appearance.
A dishwasher safe product will not only get a better clean, but also eliminate risks of them being involved in a classic rough-handed sink wash that smashes the odd glass or three. Microwave compatibility also allows for re-heating drinks without damaging the shape or design.
Durability
Glass is not known for being able to survive falls from a great height or clumsiness and so if you are looking for a long-lasting glass it needs to promise thick, sturdy material. Of course, no type of glass is a miracle worker, but it helps to know if your item is scratch-resistant, thick and sturdy.
Handles
Weirdly, we feel like this is a commonly overlooked factor when buying mugs and cups, as it’s a given the handle should be a simple and faultless shape. But in the quest for style, many mugs and cups get it oh so wrong and others neglect having one at all. So just remember, being able to properly hold your glass is absolutely everything!
