The Mushroom bowl is the silicone version of the famous El-Nefes clay bowl that usually comes with Kamin heat management grids.
The Mushroom bowl is really adapted for heat management grid use. It has the advantage to be unbreakable and to have elevated holes if you're smoking juicy steam stones or shisha tobacco.
The Mushroom bowl is compatible with numerous heat management systems such as Kamin grids, Kamin Sets, Volkan, Phoenix, Birdhunter, etc...
It can be used with a large MOD grommet.
