Wil Menzies provides a basic foundation for making a clean, round marble in this tutorial. He shares a glass “skinning” technique passed down to him by Lewis C. Wilson that can also be used in other forms of solid glasswork such as paperweights and sculptural pieces. This article was originally published on page 28 in the Summer 2013 issue of The Flow.
