    I have found that in order to manipulate the "silver glass" or Double Helix brand glass you need to use a reducing flame - meaning low oxygen - in order to get the desired effect. If the flame is oxygen rich the effect will come out muddy. Here is some reading on reducing with lampwork glass:http://envisionsf.blogspot.com/2009/04/silver-glass-101-reducing-silver-glass.html

    Here is a video: http://www.youtube.com/watch?v=IWlrkgHzFVc

    The following Thompson Leaded colors will give a raku look when reduced with a flame. If you torch fire these enamels from underneath and then finish up with playing the torch over the top surface you will get an iridescence on the surface. These are colors that were tried at the Steve Artz workshop.
