What Is Borosilicate Glass?

Double Amber/Purple Borosilicate Glass

The type of glass used in all the cremation jewelry and ash art on this website is called “borosilicate glass”. It’s a specialized and versatile variety of glass developed by Corning, Inc. in upstate New York. It’s far stronger than the “soft” glass that is normally used for beads, ornaments, paperweights, art glass bowls, etc.

It is so strong that it’s been used for everything from stove top cookware to nuclear waste containment. Scientific glassware such as beakers and test tubes are good examples of utilitarian items made of this glass because of its superior strength.

Chemical Composition of Borosilicate Glass

Molecularly speaking, this glass differs from regular “soft glass” in one simple way. Borosilicate glass substitutes particles of boron oxide for the soda and lime particles found in soft glass. The boron oxide “glues” the silicate particles together with aluminum oxide and sodium oxide. Because the boron oxide particles are small, the silicate is bonded together more tightly which results in a much stronger glass.

 

Borosilicate Glass Has A Longer Lifetime

The main reason I prefer to work with this glass is that the finished glass art is much more durable. This is especially important when creating cremation jewelry. This glass is a lot less sensitive to day-to-day mishaps and it can last for generations. Many people have commented on how many “accidents” their cremation jewelry survived without breaking or cracking.

 

Borosilicate Glass Has A Natural Color Palette

The second major reason I prefer this glass is the available color palette. Each color is an organic, living collection of hues that can be manipulated and shaded with careful torch work and kiln annealing. The colors that can be achieved using borosilicate glass are more dynamic and subtle than most soft glass colors. Also, due to the chemically compatible composition of this glass, various precious metals like silver and gold can be used to color the glass in some very unique and amazing ways.

Galaxy Cremation Bead Review by Christa Medders

I was out of town when my pendant arrived but my husband took a photo and posted it for me so I was very excited to get home and see it. It is absolutely perfect in every way. I wore it to work the day after I got home. Everyone who sees it loves it.

It is obvious it was made by a person with a lot of emotions and good karma; it comes through in the piece. I will always treasure it and I thank you for it’s beauty and craftsmanship. And thank you for your kind words about Daniel. This pendant will always keep him close to my heart.
