California-based glass artist Loren Stump specializes in a form of glasswork called murrine, where rods of glass are melted together and then sliced to reveal elaborate patterns and forms. While the murrina process appeared in the Mideast some 4,000 years ago, Stump has perfected his own technique over the past 35 years to the point where he can now layer entire portraits and paintings in glass before slicing them to see the final results. His most complex piece to date is a detailed interpretation of Leonardo da Vinci’s Virgin of the Rocks, which involved hundreds of glass components that were melted into a final piece.
