Some people are skeptical about using a glass pitcher for holding boiling water and hot beverages such as coffee or tea. It is a reasonable prerogative as many of us have experienced pouring hot liquid into a glass container and ended up breaking it. But this is not always the case.
Specifically made to withstand high temperatures, the best glass pitchers can hold hot drinks for a long time, and they will not crack. With extra care, you can even pour boiling water into these glass pitchers without shattering them.
A generic glass pitcher, made of ordinary glass, undergoes expansion when subject to heat. Once you pour boiling water into the glass, the inside part of the glass expands due to heat while the outer layer remains cool. The temperature difference will cause the inner layer to expand far greater than the outer part.
The discrepancy in the amount of expansion between the inner and outer parts will create stress, which at some point will exceed the glass’s tensile strength. Once exceeded and the glass can no longer contain the pressure, also known as thermal shock, it will start to crack.
To be on the safe side, always use heat-resistant glass pitchers for your hot beverages.
Typically constructed of borosilicate glass, which is known to have a very low thermal expansion coefficient, they are more resistant to thermal shock than other glassware. They will not break under extreme temperature changes.
The coefficient of thermal expansion indicates the rate at which the glass expands when exposed to heat. The higher it is, the greater the tendency of the glass to react to heat by expanding. With a low thermal expansion coefficient, borosilicate glass can withstand high temperatures without drastically changing its shape, area, volume, or density.
The effect of thermal shock is powerful and results in the cracking of glass. Even heat-resistant glasses like Pyrex can shatter when poured with boiling water incorrectly. To prevent the glass from cracking when exposed to boiling water, you should avoid extreme and abrupt changes in temperature. You can accomplish this in different ways.
Pour the boiling water gradually
By pouring the hot water into the glass pitcher gradually, you will allow the glass to adjust slowly to the water’s high temperature, reducing thermal shock.
Use a metal spoon
Metal is an excellent heat conductor. When you put a metal spoon in the glass pitcher and slowly pour the water over the spoon, it will absorb some heat. This helps cool down the water that contacts the glass’s inner layer, minimizing its temperature deviation from the outer layer.
Warm up the glass
Another effective way to prevent breaking your glass pitcher when putting boiling water into it is to warm it up first. Before filling the glass, rinse it with 50% tap water and 50% boiling water; the outer layer first, then the inside part. By exposing the outside to heat, you let it expand before pouring the entire boiling water into the bottle, which means less thermal shock.
Pouring boiling water into a glass pitcher can be tricky. The key is to reduce the temperature difference between the inner and outer layers. By minimizing thermal shock, you can enjoy a no-worry, shatter-free pour.

In these modern times,we see different pitcher variations made from a wide array of materials, specialties and designs. However, according to GMP (Good Manufacturing Process), the most recommended material for food and beverage containers based on safety and recyclability is GLASS.
To briefly discuss this point, cans made of glass are BPA-free and their non-porous nature makes them resistant to leaching and chemical attack. In terms of recycling rates, glass has unlimited availability, while plastic materials are not recommended for longer periods of time.
First, we need to look at what type of glass material it is made of.
There are two types of glass commonly used to make water pitchers. Soda lime silicate glass and borosilicate glass.
Of the other types of glass, soda lime glass has undergone the least amount of tampering and manufacturing. This glass appeared in its most basic soda-lime silica form when it was first discovered. Many of today's windows, bottles and kitchenware are made of soda lime. In addition to being an abundant base material, soda lime is also very inexpensive.

Many manufacturers choose this material because of its low production costs. However, compared to borosilicate glass, soda lime is somewhat lower in terms of durability. It is prone to heat shock failures and can barely withstand extreme temperatures.
Borosilicate glass, on the other hand, is made from a mixture of silica and boron oxide. This type of glass is very popular in laboratories because of its durability and unparalleled resistance to thermal changes and chemical corrosion.
Due to its low coefficient of thermal expansion, this type can withstand extreme temperatures. It is for this reason that many quality kitchenware (especially those that are frequently subjected to heat) are made from this type of glass. As you can see, this is where the biggest difference between soda lime glass and borosilicate glass lies, which gives the latter its outstanding quality.
Glass Serving Pitcher
The DINGMU water pitcher is made of durable high borosilicate glass, which has good heat resistance. The extra-wide carafe mouth allows you to easily reach in and dlean the carafe. It can be washed in a dishwasher, but hand washing is recommended.
For safety reasons, always use heat-resistant glass pitchers for hot beverages.
Usually made of borosilicate glass, which is known to have a very low coefficient of thermal expansion, they resist thermal shock better than other glassware. They will not break under extreme temperature changes.
The coefficient of thermal expansion indicates the rate at which the glass expands when exposed to heat. The higher it is, the greater the tendency of the glass to react to heat through expansion. Borosilicate glass has a low coefficient of thermal expansion and can withstand high temperatures without significantly changing its shape, area, volume or density.
Glass Water Pitcher with Lid
Some people are skeptical about using glass water pitchers for boiling water and hot beverages such as coffee or tea. This is a legitimate privilege, as many of us have experienced pouring hot liquids into a glass container and eventually breaking it. But that's not always the case.
Made specifically to withstand high temperatures, the best glass water pitchers can hold hot beverages for long periods of time and not break. With extra care, you can even pour boiling water into these glass water pitchers without breaking them.
The DINGMU glass water pitcher with lid is made of excellent quality borosilicate glass that can withstand instantaneous temperature changes from 30°C to 150°C. Designed with a built-in filter lid, it makes the perfect tea or fruit infusion.
Borosilicate glass carafe is the most common type of beverage server used in homes and restaurants or food service establishments. We offer a wide variety of wholesale glass water pitchers in a variety of sizes to suit our customers' needs.
