What is Borosilicate Glass?
Borosilicate glass is a very unique and specialized variety of glass. Its composition is different from the “soft” glass that is normally used for beads, paperweights, art glass bowls, ornaments, etc. Borosilicate glass is far stronger than “soft” glass and has been used for everything from stovetop cookware to nuclear waste containment. One of its most frequent uses is to make scientific glassware such as beakers and test tubes. Chemical Composition Chemically speaking, borosilicate glass substitutes boron oxide particles in place of the soda and lime particles found in soft glass. The boron oxide serves as a flux or glue to hold the silicate particles together with aluminum oxide and sodium oxide. Because the boron oxide particles are so small, the silicate is held together more closely resulting in a much stronger glass. Borosilicate glass is also highly resistant to the strongest of chemicals and acid compounds. Unusual Durability! One big reason we prefer to work with borosilicate
Borosilicate was developed originally for cookware (trade name PYREX) and scientific glassware such as test tubes. This makes borosilicate glass much more durable than soft glass (soda lime) which is used to make most glass beads, art glass vases, ornaments and paperweights. The durability of borosilicate glass makes it a great product to use for glass beads. Another major reason for using borosilicate glass is the amazing color palette available. There are actually fewer colors available to work with but each one is an organic, living color that can be manipulated and shaded with careful torch work and annealing. The finished piece appears much more dynamic and vibrant. Also, because of the chemical composition of borosilicate glass, different precious metals such as silver and gold may be used to color the glass in some very unique and amazing ways.
It is the same kind of glass used in laboratories due to its superior strength, durability and ability to resist thermal shock, making it extra safe for your little baby. Borosilicate glass is also much lighter than traditional glass that is used for baby bottles.

Borosilicate glass is a type of glass which includes at least five percent boric oxide. The boric oxide makes the glass resistant to extreme temperatures, and also improves its resistance to chemical corrosion. This glass is very popular in the manufacture of scientific instruments, and it was once widely used to make glass for kitchens as well. Today, soda-lime glass is the glass of choice for kitchenware, due to the fact that it is generally cheaper to produce than borosilicate glass. Invention of borosilicate glass is generally credited to Otto Schott, a German glassmaker who worked in the 19th century. By the late 1900s, the process for making borosilicate glass had been refined, and in 1915, a famous line of borosilicate kitchen products was released under the Pyrex label. Because borosilicate glass is stronger and more durable than conventional glass, it has a number of far reaching uses. This glass is not invincible, of course. It will crack if subjected to very sudden and radic
