I had the pleasure of attending a demo by Laurie Nessel on Monday. She used a bench minor to create a fabulous marble from soft glass. If you are in the Phoenix area, I highly recommend attending her informative flameworking class.
On another note, the pictures were taken with a new Nikon D3200 24.2 MP Digital SLR with 18-55mm f/3.5-5.6
AF-S DX VR NIKKOR Zoom Lens with UV filter from 3 feet away, no flash, no tripod. I'm thrilled with the quality of the photo. I look forward to discovering the limits of my Nikon in future lampwork tutorials.
