Borosilicate glass was first developed by German glassmaker Otto Schott in the 19th century. Corning Glassworks brought this glass to the US market in the 1920s. It has been widely used in industrial applications, test tubes, lab beekers, and in kitchens everywhere. But nowhere is it more beautiful than when we blow beads and other articles for jewelry. Handmade in Murano working at temperatures in excess of 2200 F, it makes a sturdy and beautiful lightweight bead.
