Karen is a veteran glassblower, having started her career way back in the mid-90's. She was one of the original early marble artists paving the way back then, and while some of these early historic pieces don't show the tightness of design that we see in today's artists, she was a trailblazer back then and these were COOL as heck, with sweet elements that we'd never seen in small marbles before that! She works with soft glass on the torch, and sadly we have so few soft glass torchworking marble artists left these days. Her designs are all beautiful, playful and very colorful! This one has green/blue dots, with with sweet squiggly cane lines between those dots! Super historic marble right here, signed 'Karen Federici 98'.
