Eric Ross 4.0 - Quartz Bead 12mm

12mm Outer Diameter

6mm Inner Diameter

These quartz beads can hold a lot of heat at 6mm thick. You can heat them inside of your quartz bucket. They come in 2 lengths (12mm and 25mm)

The benefit is more surface area than a solid piece, and heat retention similar to the bottom disc of the Fountain.

Both sizes work in the T6 Fountain.  The 12mm length is great for the T4 Fountains.
