Although a cup of coffee on its own is wonderful—especially first thing in the morning when you’re craving a robust brew—coffee delivered in a beautiful glass seems to satisfy much more.
Perhaps you’ve seen some stunning images of handmade coffee served in fancy glasses online and thought to yourself, “I’d love to attempt that sometime. Is it safe to do that?”
Is it safe to drink hot coffee out of a glass mug? Putting hot coffee in a glass is fine, but only use heat-safe cups to avoid serious damage. Make sure the glass you’re using can withstand high temperatures without shattering.
If you want to drink your coffee from a glass without getting burned or having to deal with broken glass, keep reading to learn more about the appropriate and inappropriate times to do so.
Can I Put Hot Coffee In Any Glass?
You can’t just pour hot coffee into any glass since doing so could cause the glass to break and the combination of hot coffee and broken glass could hurt you. To avoid thermal shock, which could cause the glass to fracture when you pour hot coffee into it, make sure the glass is suitable for usage with high heat.
When the coffee is hot but the glass is cool, thermal shock occurs, and the glass breaks. Additionally thin and more prone to cracking when exposed to high temperatures are some glass cups.
Although you would need to check this first before using them for your hot coffee, there are some heat-proof, temperature-resistant glasses that can be used for hot coffee.
How Do I Know If I Can Put Hot Coffee In A Glass?
Glasses can either withstand high temperatures or they cannot. A regular glass cup that is not resistant to high temperatures will work fine in temperatures ranging from 20°F to 150°F, but anything above will cause it to break.
Heat-resistant glasses are composed of high-borosilicate material, which is thicker and more durable, and can withstand hot coffee and other hot liquids without cracking or shattering.
To determine whether a glass is heat-resistant, look for a heat-resistant stamp on the glass. This is most likely under the glass’s foundation. If you notice this label, you can safely pour hot coffee into the glass.
If the glass lacks this heat-resistant stamp, you should avoid pouring hot coffee into it because the possibility of it breaking is significant, and you don’t want to inflict unnecessary injury and mess.
What Happens If I Put Hot Coffee In An Unsuitable Glass?
Pouring hot coffee into a non-heat-resistant glass will likely cause the glass to split and shatter. This may not occur frequently, but it only needs to occur once to create harm (and a huge mess).
The abrupt exposure to heat will cause the glass to break and crack, and the coffee will spill everywhere. These glasses were not designed to withstand quick temperature fluctuations and high heat, thus they will shatter.
Can Heat-Resistant Glasses Shatter?
As we already discussed, the ideal choice to make when pouring hot coffee into a glass is to select a heat-resistant glass to ensure the glass can withstand the heat. But even heat-resistant glass can break occasionally, and this happens when the glass undergoes thermal shock.
Thermal Shock And How To Avoid It
Thermal shock occurs when a cool or room-temperature glass is subjected to excessive heat from a liquid, causing the glass to expand too quickly and shatter. When pouring hot water into a glass, there are some precautions you should take to avoid cracking it. Here are several methods for avoiding heat shock.
Don’t Pour Too Quickly
Avoid rapidly putting the hot coffee into the glass; instead, pour it in gradually. This allows the glass to gradually acclimatize to the higher temperature and should prevent thermal shock. Pour a small bit of hot coffee into the glass, wait a few seconds, and then carefully pour the remaining coffee into the glass.
Warm The Glass Before
When hot water is poured into glass that is at a lower temperature than the water, a phenomenon known as thermal shock occurs. This can lead to the glass shattering. You can avoid this by first warming the glass and then filling it with hot water.
First, fill it halfway with tap water, then add boiling water. This is the most effective approach to clean it. Doing so will preheat the glass for the incoming hot beverage.
Place A Metal Spoon In The Glass
Putting a metal spoon into the glass is a simple tip you can employ to avoid thermal shock. Due of its high thermal conductivity, metal will absorb some of the heat from the hot water, reducing the risk of thermal shock. Pour the hot coffee into the glass over the metal spoon first, allowing the spoon to absorb heat before it hits the glass.
What Is The Best Cup For Coffee?
If you want to avoid glass in order to avoid shattered shards and spilled coffee, you need know what the greatest coffee cup is!
Is Ceramic A Safe Material?
Ceramic is widely regarded as the best material for consuming hot coffee. Ceramic can withstand high heat (check the cup to ensure this) and keeps coffee warmer than glass. There are a variety of ceramic coffee cups and mugs available, so you may choose the one you like most for your coffee!
Will A Glass Cup Keep Coffee Hot?
Another reason why you shouldn’t use a glass cup is that it won’t do a good job of keeping your coffee hot for long. Also applicable to glasses that can withstand high temperatures. Even though the coffee is piping hot when you pour it in, it will cool quickly and lose much of its appeal if you wait even a few minutes.
Can You Put Hot Coffee In A Regular Glass?
You can pour hot coffee into an ordinary glass, but you should look for a heat-resistant glass that won’t break under intense heat. To prevent thermal shock, which happens when the temperature of the glass changes too quickly and it breaks, you must slowly pour the coffee into the glass (or warm the cup up first), even when using heat-resistant glass.
If you choose the correct glass to hold your hot coffee safely, your coffee will look beautiful in a glass cup and won’t be affected by glass at all in terms of flavor.
Is Stainless Steel Good For Hot Coffee?
Stainless steel coffee cups are great for hot coffee, especially if you need a travel cup. They are extremely sturdy, do not shatter easily, and can withstand high temperatures. Stainless steel will also keep your coffee warm for a long time!
Can A Mason Jar Hold Hot Coffee?
Currently, coffee in a mason jar is a popular aesthetic; nevertheless, you need act with caution if you wish to replicate this at home. The majority of mason jars are not heat-resistant, and there is a possibility that the glass will shatter.
It may be possible to use Mason jars for hot coffee for an extended period of time, but there is always a chance that they will crack, therefore it is recommended to avoid doing so. If you truly want to enjoy coffee in a mason jar, iced coffee is the finest option!
Can you put hot tea in a wine glass?
No. Putting hot tea in a wine glass is not a smart idea, especially if the glass is not marked as heat proof. There’s a risk that the tea’s heat will crack the glass, rendering both the tea and the glass useless.
Can a drinking glass go in the freezer?
No and yes. A drinking glass can be put in the freezer because it has a low freezing point and can’t truly freeze, but we don’t suggest keeping it there for an extended period of time. However, before using a drinking glass for a cocktail or other cold beverage, you can put it in the freezer for a brief period of time.
Obviously, you may put most glass storage containers in the freezer, but they usually are composed of tempered glass, which, when used properly, can endure the freezing temperatures for a long time.
