One of these days I will feel like I can offer marbles for sale.
My fist semi-successful fumed glass marble. Still need to work on my putty handling and tube handling. Of course they make it look so easy in the videos.
Fuming is a technique that has been developed in the past 15 years and was popularized by Bob Snodgrass. Fuming consists of heating silver or gold in the flame, so that the metals vaporize or “fume” microscopically thin layers of particles onto the glass. These particles stick to the hot glass surface changing its color with interesting effects. Silver turns clear glass into a yellowish color, giving shades of blues and greens when backed with a dark color, while gold turns clear glass shades of pinks and reds. The precious metal coating becomes increasingly visible the more the glass is fumed.
