These glass nuggets work best when you pull them into thin stringers. Just preheat a few in a hot kiln. Use tweezers to take them from the kiln to the flame. Pull thin stringers as the gather starts to melt.
When left slightly raised on the surface of a bead, either as dots or line patterns, this glass makes the prettiest golden/silver metallic luster when reduced. For this effect, simply flash the bead quickly in a 'reduction' flame (less oxygen/more propane) right before you put the bead in the kiln for annealing.
