4 Primary Benefits of Using Glass Coffee Mugs
Here, I am providing few benefits of drinking coffee in glass cups.
1. Clean Transparency:
While you are brewing your coffee, you can have a look to judge the color and concentration of your coffee.
You can make it the way you like because of the transparency of a glass coffee cup.
2. Aesthetically Appealing:
Glass is microscopically perfect with a smooth and leveled surface.
In comparison to a glass mug, a ceramic coffee mug has meticulous roughness causing the particles to rub against the surface.
3. Easy To Clean:
Glass is a pore-less material making it comparatively easier to remove the stains.
The tinges do not incorporate in the glass mugs as happens in ceramic coffee cups.
You can even wash them in the dishwashers with your regular cleaning dishwashing soap.
4. Eco-Friendly Material:
Glass coffee mugs are environment friendly too.
They can be recycled and have a low carbon footprint.
Glass mugs are also safer than using plastic coffee cups such as Solo cups.
They are prepared from raw material free of chemicals.
Glass mugs, unlike plastic cups, will not release any carcinogenic or harmful material in your coffee.
Does Glass Mug Keep Coffee Hot and for How Long?
A glass coffee mug with double insulation keeps coffee hot for much longer period.
It is because these types of cups or mugs have some air gap between the two glass layers.
The layer of still air makes the coffee stay hot.
But contrary to this, glass is a good heat insulator.
So, the absorbed heat will not stay for a longer time and your coffee will get cold.
Thus, double walled glass coffee mugs keep your coffee hot for around 10-20 minutes until all the heat is lost to the surroundings.
To avoid the stale taste of coffee, consume it quickly after pouring it into a glass cup.
Can You Store Coffee in a Glass Cup in Fridge?
Storing coffee in the fridge is, undoubtedly, not a healthy decision for you.
It makes the freshness of your coffee go away in just few minutes.
If you keep a coffee glass cup in the fridge, the odor of other food items stored in the fridge will seep into the coffee.
This will obviously make your coffee taste unpleasant.
It is preferred to consume it within 1-2 days of its preparation if you store your coffee in a glass mug and then put it in your fridge.
You can take it out of the fridge when you need to drink it and reheat it.
If you have done this before then you must know that it won’t taste as great as the freshly brewed coffee.
The refrigerated coffee also loses its flavor and aroma in the process.
But if you don’t have enough time to brew small shots every day, then the idea of storing coffee in a glass cup will definitely work for you.
Just make sure you drink the stored coffee within 1-2 days of its storage.
Are There Any Side Effects of Drinking Hot Coffee with Glass Cup?
Glass is widely used for drinking purposes.
It can be dangerous to your health because a certain quality of glass contains lead and cadmium.
The harmful effects of cadmium include cancer, kidney stones, and osteoporosis.
Lead causes restricted growth and retardation.
Especially, the decorated glass cups are posing a greater risk to your health because its enamel contains harmful chemical substances.
However, these are exceptions and not all the glass coffee cups are dangerous for your health.
In fact, glass material itself is inert and is completely safe for drinking purposes.
It does not produce any chemical substances which will disturb your hormones, like plastic.
Even after you throw away glass; it has no negative impact on the environment.
The only disadvantage of glass to the environment is the effect of the melting process during which carbon dioxide gas is emitted.
Nowadays, you get to use double walled insulation glass coffee mugs and borosilicate glass coffee mugs.
Both of these types are most suitable and a safer option for you if you are interested in drinking coffee using glass mugs.
