Learn how to use Double Helix© striking glass to achieve a variety of color effects. Double Helix is a soft glass but can sometimes produce effects that make it look similar to some kinds of borosilicate glass.

Learn how to "reset" and "strike" Double Helix glass to change its appearance and create a variety of color effects that generally aren't possible using other methods. Learn how to encase beads in clear to further impact the appearance of the striking Double Helix glass. 

You'll see demonstrations of techniques and you'll get to practice them by making several beads with several different colors of Double Helix glass. These techniques will transfer to other objects and sculptures and marbles.

Laura Arns

Although she's a computer scientist by day, Laura Arns has been working with glass in various ways for more than 20 years during her free time. As a lampworker, she is somewhat unusual because she hasn't specialized but instead works with both borosilicate and soft glass to create beads, marbles, blown ornaments, sculptures, goblets, and more. She particularly enjoys collaborative projects with artists and artisans who work in other mediums. Over the years, she's had the opportunity to learn from numerous well-known lampworkers. A former college professor, she's looking forward to more teaching in BARN's Glass Arts Studio.
