Blaze Glass - Removable Double Coil Spiral Percolator 18.8mm - Silver Fumed
This spare spiral percolator fits into bongs with a removable percolator system with a 18.8mm female joint. The spiral not only looks cool, it cools your smoke for a smoother, tastier hit. The yellow color is achieved with silver fume in the glass firing process. Fumed glass appears to change color over time with buildup, so the looks of this piece will evolve as you use it. Thorough cleaning returns it to its original hue.
