When it comes to the type of glass used to make glassware, you may be surprised to find that there are several types of materials available. This is generally what sets apart low-quality and high-quality drinking glasses.

Even though the glass types may look similar, there are a number of quality differences when it comes to construction and what the glass itself is made of, including for two of the most popular types of glass—borosilicate and crystal  glass. They may look the same and have the same function, but we prefer classic crystal over the newer borosilicate. Here’s what this material is, and why we prefer its competitor.

What Is Borosilicate Glass?

Borosilicate glass is made from boron trioxide, which gives the glassware a low coefficient of thermal expansion, meaning it won’t crack like regular glass does when experiencing extreme temperature changes. The  flexibility and durability it ensures makes it a popular choice for a variety of different uses.

What Is Borosilicate Glass Used For?

Borosilicate is most widely known for its ability to handle extreme temperature changes and resist corrosion, making it a popular choice for construction of blender jars, Pyrex dishes, and drinking glasses.  It’s also a popular choice in labs or industrial settings, due to its resistance to chemical changes.

Is Borosilicate Glass Safe?

Borosilicate is a safe and non-toxic option for glassware since it’s resistant to chemicals as well as acid degradation, and is dishwasher- and microwave-safe. Products made from borosilicate glass can even be left in a hot car or outdoors with no fear of the release of harmful toxins into your drink like some less expensive alternatives do.

Borosilicate vs Crystal Glass

Crystal (also called “lead crystal”) is composed of silica, lead oxide, and soda or potash. It is much thinner than borosilicate, so it’s able to be etched with the intricate designs many associate with crystal. When two crystal glasses touch, they make a “clink” sound, while borosilicate makes a “clunk” when glasses touch.

Borosilicate is stronger than crystal and is a great choice for storage and blender jars, but when it comes to Glassware, we prefer crystal. These delicate glasses are not only aesthetically appealing, but are a stellar choice whether you opt for our Wine Glasses or Coupes.

While borosilicate is a fine option, crystal glass has stood the test of time when it comes to both safety and aesthetic appeal. Crafted in Italy, our Glassware is dishwasher safe and features titanium-reinforced stems, making it as durable as it is elegant.
