4.7mm silicon nitride spheres.


High purity, low surface adheshion, good thermal shock value.


Designed specifically to fit our Halo and Nimbus dishes, they also fit... basically everything.


Note:  Please do not use these or any spheres without lubricant.  Use of multiple spheres can cause them to slide instead of roll, which can risk damage.

    SiC comet

    Posted by Kamogawa on Feb 2nd 2020

    I was eager to do some testing of my own and brought a few comets to try in various different dishes/bangers. I was already used to mixing the material and spreading it across the dish but was dreaming of how to carp cap it at the same time to retain the low temp longer! Comets in bangers act as excellent heat retainers and help mix the material. However nothing compared to the magic that happens when you combine the comets with a halo dish or a nimbus dish in junction with a directional carb cap! Simply drop the material into the dish and cover with the directional carb cap as you draw the vape in. The directional carb cap, directs air into the dish like a turbine, which pushes the comet and your material around the dish rapidly. You can feel and hear each rotation as it glides. I feel like comets work best with the Nimbus or Halo line dishes. We preferred the deeper dish of the nimbus.
