In this post, we will look closely at the difference between Borosilicate glass vs stainless steel.

In this journey, we will uncover the mysteries of Borosilicate glass and stainless steel, two materials that cohabit quietly in our kitchens and homes and play an important role in our culinary adventures.

From the crystal-clear brilliance of glass to the durable strength of steel, let’s take a journey to grasp their properties, applications, and which one might just steal the spotlight in your daily life.

Are you prepared to discover the secrets of these kitchen companions? Let us dive in!”


Borosilicate glass vs Stainless steel

Borosilicate glass and Stainless steel have some similarities in terms of durability and versatility depending on the use.

Find below the difference between Borosilicate glass and stainless steel:

To begin, for open flame use on a gas stove or other source, stainless steel is a better choice than Borosilicate glass.

Borosilicate glass is a form of glass composed of silica and boron trioxide, whereas stainless steel is a metal alloy consisting of steel, chromium, nickel, and other metals.

Stainless steel is more durable and stronger than Borosilicate glass, which is prone to breaking.

Borosilicate glass is significantly easier to clean than stainless steel, particularly when it comes to cookware.

Borosilicate glass must be handled with caution because of its nature and fragility, whereas stainless steel can tolerate harsh and high-traffic environments.

In terms of keeping drinks hot or cold for extended periods, stainless steel cups/mugs outlast Borosilicate glass.

While both borosilicate glass and stainless steel are known for their strong resilience to thermal shock, laboratory equipment, and chemical durability, stainless steel is favored for highly corrosive environments as well as the manufacture of heavy laboratory applications.

Finally, the primary distinction between Borosilicate glass and stainless steel is their respective material composition/properties and applications.


One common home and kitchen item we use every day is the electric kettle and they come in various materials which include stainless steel and Borosilicate glass.

Sometimes you would find an electric kettle having a combination of both Borosilicate glass and stainless steel body structure for optimal performance.

Find below the major differences between Borosilicate glass and stainless steel kettles:

An electric kettle or stovetop kettle made with stainless steel is more durable and scratch-resistant compared to a Borosilicate glass kettle (electric or stovetop kettle) which can shatter if dropped, if the material is poor or hit with a hard object.

Stovetop Deluxe Stainless steel Tea Kettle

Borosilicate (electric or stovetop glass) kettle has quick heating time speed because of the thin layer of glass design but stainless steel kettles have a thick layer of stainless steel that might slow down the heating process.

Borosilicate glass kettle requires more cleaning but stainless steel is more resistant to stain and doesn’t require much cleaning.

Depending on the brand, both Borosilicate glass and stainless steel may be affordable and also expensive, examples of affordable Borosilicate electric glass kettles include:

A low-quality Borosilicate glass can fracture during usage, and an inferior stainless steel kettle will leach harmful substances into your water kettle.

Consider using only high-quality Borosilicate glass and a stainless steel kettle to get the best results for your needs.

If you require an economical, crystal-clear, and sleek kettle design, we recommend you pick for Borosilicate glass; but, if you need a sturdy and low-maintenance kettle, you should opt for stainless steel.

Finally, you can choose either a stainless steel or a borosilicate glass kettle; the key thing is to choose the one that best suits your lifestyle, needs, and price.


As the name sounds, Borosilicate glass water bottles are containers made from a type of glass known as borosilicate.

This glass is resistant to thermal shock, making it suitable for both hot and cold liquids without compromising the integrity of the bottle.

The primary function of these bottles is to provide a safe and durable way to carry, store, and consume water and beverages.

These water bottles are popular among individuals who prioritize health and sustainability.

They are commonly used by people who want a non-toxic alternative to plastic bottles and appreciate the durability of glass.

The transparency of borosilicate glass allows users to easily monitor the cleanliness of the bottle and the contents inside.

Borosilicate glass water bottles are chemically durable has an easy-to-clean surface.

What sets them apart from other water bottles, especially plastic is their ability to withstand high temperatures without leaching harmful substances and their overall sturdiness.

Finally, we can agree that Borosilicate glass water bottles are valued for their safety, durability, and versatility in handling various temperature conditions, making them a preferred choice for those seeking a healthier and more eco-friendly hydration option.


Glass water bottles are inert, don’t retain odors or flavors, but can break while Stainless steel bottles are durable, lightweight, and keep liquids at temperature, but may affect taste slightly.

Why would stainless steel water bottles taste slightly different? Now, you have to understand that stainless steel is an iron-based alloy that contains chromium, nickel, and other elements.

The Presence of chromium gives stainless steel its corrosion resistance, while nickel enhances its luster and formability.

Some persons are allergic and sensitive to nickel; prolonged exposure could lead to itching and redness though the leaching of nickel in stainless steel is very low and would require acidic or high-temperature conditions to occur.

304 Safe Stainless steel water bottle

Another potential health risk of using stainless steel water bottles is low-quality stainless steel bottles that may include lead in the paint or solder used during production.

What’s the way out? Use high-quality food-grade stainless steel known as the 304 or 18/8 stainless steel water bottle.

Finally, consider your priorities for durability, weight, and taste when choosing between glass and stainless steel water bottles.


Stainless steel containers are durable, resistant to corrosion, and offer good insulation. They’re also less prone to breakage compared to glass.

Stainless steel food storage container

Glass containers, on the other hand, are non-reactive, don’t retain odors, and are microwave-safe. However, they can break easily and are heavier than stainless steel.

Glass food containers are less insulating than stainless steel food containers.

Stainless steel is non-corrosive and can keep drinks hot or cold for longer hours than glass containers.

Stainless steel food containers are a preferred option for travel because of their weight and resistance to breakage more than glass containers.

The choice depends on your priorities, such as durability, weight, and the type of usage.


Both glass and stainless steel are safe materials for drinking, but they have distinct characteristics.

Glass is inert, doesn’t impart any flavors, and is easy to clean.

Stainless steel is durable, unbreakable, and retains temperature well.

Choose based on your preferences for taste, durability, and maintenance.


First, let me clarify that the term “glass” in this context refers to “regular or ordinary glass.” In the previous article, I detailed the distinctions between Borosilicate glass and regular glass, but this time we will apply it to a water kettle.

Regular glass kettles are transparent, allowing you to see the water boiling. They are prone to breaking if mishandled.

Stainless steel kettles are more durable, resistant to damage, and retain heat well. However, they don’t provide visibility into the boiling process like glass kettles do.

Regular glass isn’t suitable for open flames or electric kettles as they can’t stand extreme temperatures.

The right kind of glass to use for water kettle purposes is Borosilicate glass which I have already explained above.

Finally, when it comes to stovetop or electric water kettle use, Stainless steel should be your go-to choice and not regular glass.


The best materials to use for hot water are stainless steel, glass, and lead-free ceramic since they are long-lasting and do not leach dangerous elements into the water.
