Style 13A - 1.50" Diameter x 4.5" Cylinders
 with TWO Charge Layers


These cylindrical specimens were carefully cut and polished, then irradiated on two sides to create a two side-by-side dendritic trees.  The cylindrical shape tends to magnify the internal patterns and, when illuminated from below using a color changing light base, the internal figures sparkle and glow beautifully. Discharge may be either parallel planes, Windblown Lightning, or a mixture of the two. A few also self-discharged, creating a mix of chaotic and dendritic patterns.  These specimens work quite well with our BD752MC, BD753MC, CR35MC crystal multicolor bases, and our ROT45MC rotary light bases. They they also work quite well with the bright white LM2690 or LM2692 rosewood light bases.  Although the fractal patterns vary from piece to piece, your satisfaction is always guaranteed.

Self-Discharged Dense Dual Dendritic specimen on a CR35MC  multicolor crystal light base. Some specimens have a bit of chaotic discharges as well.

Same specimen on left, different color illumination.
When this specimen self-discharged while being irradiated, it created a gorgeous, very dense set of interlinked discharges.

Same specimen as on left, rotated 90 degrees. Magnified image appears to fill entire specimen.
