Borosilicate glass is a well-known household name due to its many advantages; it is also useful in a variety of applications, especially in the medical and laboratory sectors.
Even though borosilicate glass has many applications, glass enthusiasts remain plagued by two questions: first, is borosilicate glass truly biodegradable, and second, is borosilicate glass crystal?
Knowing the difference between crystal and borosilicate glass enables consumers to choose the right glassware for their needs preventing home accidents and getting the best result.
Beyond functional concerns, this understanding deepens our appreciation of the craftsmanship and creativity that go into each piece, enhancing our celebrations and daily routines.
Together, we will explore the properties of borosilicate glass and determine if it can be classified as a crystal.
WHAT TYPE OF GLASS IS BOROSILICATE GLASS?
Borosilicate glass is a type of glass that contains boron trioxide, which gives it a very low coefficient of thermal expansion.
This makes it highly resistant to thermal shock, making it suitable for laboratory glassware, kitchenware, and some high-end consumer products like high-quality cookware and glass pipes.

WHAT TYPE OF GLASS IS CRYSTAL?
Crystal glass is a specific type of glass that contains lead oxide. It’s known for its clarity, brilliance, and ability to refract light, making it popular for high-end glassware, such as wine glasses and decanters.
IS BOROSILICATE GLASS CRYSTAL?
Borosilicate glass is not crystal. They don’t have the same constituents, Crystal glass contains lead oxide, which gives it its brilliance and clarity.
Borosilicate glass, on the other hand, is made primarily from silica and boron trioxide, making it more resistant to thermal shock and better suited for applications like laboratory glassware and kitchenware.
BOROSILICATE GLASS VS CRYSTAL
Find below the differences between Borosilicate glass and Crystal glass:
Borosilicate glass is more resistant to thermal shock, making it suitable for high-temperature applications than Crystal glass.
Borosilicate glass is commonly used for laboratory glassware, kitchenware, and lighting fixtures while Crystal is prized for its beauty and is often used in fine glassware, chandeliers, jewelry, and decorative items.
Borosilicate glass is free from lead and doesn’t leach toxins but some brands of crystal glass might contain lead content.
Borosilicate glass is highly resistant to chemical corrosion and breakage but Crystal glass is not.
Borosilicate glass lacks the lead content essential for the crystal’s hallmark sparkle and weightiness.
Crystal glass is more delicate and prone to chipping or cracking, especially when exposed to sudden temperature changes making Borosilicate glass more durable than Crystal glass.
Crystal glass has a higher refractive index due to the lead content, giving it greater brilliance and clarity than Borosilicate glass.
Finally, in terms of constituents, Borosilicate glass is typically produced using a process that involves melting together silica sand and boron trioxide at high temperatures while Crystal is made by adding lead oxide to the silica mixture, which lowers the melting point and improves the glass’s optical properties.
IS PYREX CRYSTAL?
Pyrex is not a crystal; they both have different characteristics and chemical makeup. It’s a type of glass known for its durability and resistance to thermal shock.
Pyrex is a name used by glassware brands for manufacturing measuring cups, bakeware dishes, mixing bowls, and other household items.
Pyrex brands are either made up of Borosilicate glass or tempered soda lime glass.
IS CRYSTAL AND GLASS THE SAME THING?
No, Crystals are not the same as regular glass; they don’t contain the same constituents and therefore don’t have the same qualities.
For example, crystal glass is typically thinner, more durable, and has a higher refractive index, resulting in greater brilliance and sparkle than regular glass.
In addition, Crystal glass is often used for fine dining and decorative items due to its elegance and premium feel.
HOW CAN YOU TELL IF GLASS IS CRYSTAL
There are several methods for determining if your glass is crystal or not, see below for the various methods:
The quickest and easiest way to know if your glass is crystal or not is to search for the manufacturer’s markings or labels that indicate it as crystal.
Clarity and sparkle are further indicators of crystal glass. Crystal often has a higher refractive index, thus it reflects light more brilliantly than plain glass.
Crystal’s density also causes it to emit a melodic tone when lightly tapped. For further information, please see this article: Is Mikasa made of glass or crystal?
IS BOROSILICATE GLASS CERAMIC?
No, borosilicate glass is not ceramic. It’s still classified as a type of glass, albeit one with specific properties due to its composition, notably its low thermal expansion coefficient.
Ceramic materials are typically non-metallic, inorganic solids made through the process of heating and cooling, but they have different properties and applications compared to borosilicate glass.
IS BOROSILICATE GLASS CONDUCTIVE?
No, Borosilicate glass is not conductive. It is an insulator, meaning it does not conduct electricity.
