These gorgeous cobalt and multicolored beads are created by using a torch and metal tools in the complex and delicate process of lampworking (also called ''flameworking'' or ''torchworking''). While modern glass artists use gas-fueled flame torches, this kind of glasswork was originally done over an oil lamp, thus the term ''lampwork glass.'' Colors can include cobalt, light blue, green, pink and white. Sizes, shapes and colors may vary with handcrafted items. Items are made with solid color glass, which means the base color of the glass is saturated throughout the object and will not fade or rub off over time.
