Out of the Lab and onto the Jewelry Designer's Bench

 Those new to Jewelry design usually begin with simple components - Czech glass and plated metal beads, stringing wire, crimp beads and a clasp.  But as they soon discover, beading includes a wide array of options that often surprise and inspire the designer to attempt new techniques and materials.  Often, they are surprised to learn the background of some of the materials commonly used.  For instance, iKandies often uses boro glass in its designs.  Boro glass teardrops were used in our Copper Leaf and Glass Autumn Necklace and boro glass cubes were used in our Raspberry Seed Bead and Boro Glass Necklace.  What is boro glass?  


Boro glass is borosilicate glass, a type of glass that consists of about 10% 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 in the scientific lab. This glass is also used for reflecting telescope glass mirror components because the optical surfaces change very little with temperature fluctuations, resulting in very precise measurements.


Borosilicate glass is thought to have been created by a German glassmaker in the 19th century. In 1915 a famous line of borosilicate kitchen products was released under the Pyrex label.  Borosilicate glass is usually without color, but colored borosilicate was introduced into the market in 1986 and is used by jewelry design artists today.
