The color of this glass knob is purple Venetian Glass. It is about 1-1/2 inch round. The bumble bee is handmade first and then fused to the purple glass knob as I make it.
The lampwork technique I use includes the use of Venetian, American, Japaneese and German Glass and often with inclusions of silver and goldstone to name a few. Glass knobs are made on a durable stainless steel threaded insert designed by the artist and manufactured in the USA under the trademark MAKE A KNOB Kit. For easy installation each Glass Knob is delivered with a screw and plastic washer to protect your wood surface.
