Usually, people look for a non toxic glass water bottle that is safe and chemical-free. A borosilicate glass water bottle is one such option that you can consider for a healthy hydration routine.
This type of glass bottle is considered safer than plastic or even soda-lime glass. If you are curious to know whether a Borosilicate glass water bottle is safe, this is the article for you.
By going through the information provided below, you can have a better understanding about the safety level of a Borosilicate glass water bottle.
So, let’s dive in!
What is Borosilicate Glass and How is it Made?
Before discussing the safety level of a Borosilicate glass water bottle, it would be appropriate to talk about Borosilicate glass. Normally, glass is made of different materials, and Silica is the most commonly used ingredient.
Borosilicate glass, for instance, is made of Silica and Boron Trioxide. Both these ingredients are safe and environmentally friendly. During the formation of Borosilicate glass, some other elements like alumina and soda ash are also used.
Usually, manufacturers use different types of methods to make Borosilicate glass, including:
- Tube drawing
How is Borosilicate Glass different from Soda-Lime Glass?
Soda-lime glass is a regular glass and it is commonly used for manufacturing glass water bottles. The major difference between Borosilicate glass and soda-lime glass relates to their composition.
A Soda-lime glass contains almost 69% silicon dioxide. On the contrary, Borosilicate glass has 80 % silicon dioxide. Besides, the percentage of boron trioxide also differs in these types of glass.
Apart from their constituents, Borosilicate glass and regular soda-lime glass also differ in terms of their physical properties. Borosilicate glass is thermal shock resistant and is easy to mold.
For instance, a borosilicate glass container won’t crack if you pour hot boiling water into it. This type of glass is more resistant to acidic liquids.
Is Borosilicate Glass Bottle Safe?
Yes, Borosilicate glass is free from toxic materials, which means it is suitable for making a non toxic glass water bottle. Most top-ranked companies use this type of glass to manufacture heat-resistant and safe jugs, bottles, and cookware.
Drinks stored in a Borosilicate glass bottle taste better, as its materials don’t leach into the liquid. This is something you can’t expect from plastic bottles, as they contain BPA.
Borosilicate glass contains boron and is free from any lead or cadmium contents. As far as Boron is concerned, it is food-safe and serves as a type of shield to prevent leaching.
This suggests that the glass container made of Borosilicate is hygienic and suitable for juices and carbonated drinks. Therefore, flavors and colors don’t leach into a Borosilicate glass water bottle.
Similarly, the contents of this glass don’t leach into the food, making it highly safe. Besides, Borosilicate glass is chemically stable. This is possible due to the addition of Boron.
A borosilicate glass water bottle is better, as it doesn’t release harmful chemicals into the water when placed in the sun. On the contrary, plastic water bottles not only remove toxins but also affect the flavor of water.
In addition, the clarity of the Borosilicate water bottle helps with UV purification by placing it in the sunlight. This is because UV rays easily pass through borosilicate glass and purify the water within less time.
Thanks to its stability and thermal resistance, you can immediately refrigerate your Borosilicate water bottle after UV purification.
Are Borosilicate Glass Water Bottles BPA Free?
Borosilicate glass is BPA-free, which means containers made of it are non-toxic. However, some Borosilicate glass water bottles contain certain components that are made of BPA plastic.
For instance, the lids of most glass water bottles are made of plastic material. Therefore, it is essential to check the chemical composition of any plastic part that comes with a glass bottle.
Is Borosilicate Glass Water Bottle Durable?
Borosilicate glass is relatively more durable than regular glass. That’s why most manufacturers use this type of glass to make cookware, jars, and water bottles.
The higher manufacturing temperature of Borosilicate glass water bottles makes them highly durable. These bottles are resistant to heat and don’t expand or contract when exposed to extreme temperatures.
If you throw a Borosilicate glass water bottle on the ground, it will break but won’t shatter like a regular glass. So, a water bottle made of Borosilicate is safe to use.
Some other Aspects Which Make Borosilicate Glass Water Bottles Safe
A Borosilicate glass water bottle is better than a normal glass bottle. Here are the reasons why you should opt for this type of glass water bottle.
Borosilicate Glass Bottle is Heat Resistant
A bottle made of borosilicate glass doesn’t expand when exposed to heat. It expands only half the time of a regular soda-lime glass bottle. Due to its low coefficient of thermal expansion, a Borosilicate glass bottle is relatively more durable and safe to carry.
This feature of a Borosilicate glass bottle makes it highly suitable for traveling. You can take a glass bottle with you when going on hiking or any other outdoor activity.
Resistant to Acidic Fluids
A Borosilicate glass water bottle is resistant to acidic drinks. For instance, the beer has a pH scale of 3.3. So, storing a beer in an ordinary glass bottle isn’t safe. Therefore, we usually find beer in a Borosilicate glass water bottle.
A Borosilicate glass water bottle proves to be a perfect and safer alternative to plastic bottles. It offers you the benefits of glass, including being easy to clean, hygienic, and non-toxic. Besides, Borosilicate can be easily recycled, making it an environment-friendly and safe material.
This type of glass bottle is relatively more durable when compared to regular glass. Since it is free from toxins like BPA or phthalates, a Borosilicate glass water bottle is safe to use.
Having said that, we hope to have helped you find a non toxic glass water bottle that is safe and meets all your hydration needs.
