“Master glassblower and stained glass artist Loren Stump in California has wowed the internet with an extraordinary display of virtuosity. He created a “loaf” of glass, called murrine, out of carefully layered glass rods that, when sliced, reveal a painstakingly detailed work of art in cross-section.

"The most impressive thing about his work is that the resulting image can only be seen in its entirety after the murrini is cut…”

Self-taught, California-based artist Loren Stump is best known for his incredible skill at murrine, a 4,000-year-old technique where colored patterns or images made in a glass cane are revealed when cut in cross-sections like a slice of bread. Stump has perfected his murrine technique to the point where he can now layer amazingly detailed paintings in glass, manipulating two-dimensional murrine slices into three-dimensional forms.


These colorful objects are contemporary examples of a millennia-old glass art form called Murrine. Murrina (the singular form) is an Italian term for colored patterns or images made in a glass cane (long rods of glass) that are revealed when cut in cross-sections. The process first appeared in the Mideast more than 4,000 years ago and was revived by Venetian glassmakers on Murano in the early 16th century.

Artists working in glass design murrine in a variety of ways from simple circular or square patterns to complex detailed designs to even portraits of people. Murrine are designed by layering different colors of molten glass around a core, then heating and stretching it into a rod. When cool, the rod is sliced into cross-sections of desired thickness with each slice possessing the same pattern in cross-section.

These beautiful murrine pieces are the work of Elk Grove, CA-based glass artist Loren Stump, owner of Stumpchuck, Loren’s lampworking studio, shop and educational facility.

Californian glassworker Loren Stump is a celebrated expert at manipulating the fickle and delicate medium of glass. Known especially for his work with murrine, over 40 years Stump has mastered the technique of layering colored molten glass around a core and then stretching the whole thing into a rod.

Once cooled and cut into, a cross-section of this rod reveals intricate patterns. Think of it like an incredible detailed candy-cane.

Not only is Stump adept at making murrine that he can create figurative images within the cross-sections that are hidden until the rod is sliced, he is also able to combine the two-dimensional forms into three-dimensional objects.

Some of his work is mind-boggling and it’s difficult to imagine how he even begins to create these classical pictures by mixing molten glass together. But he does and the results are incredible.

Individual slices range in price from $5,000 to $12,000 each!
