I used this bowl recently, it stays medium heat, it doesn't get hot to that limit that ruins the flavour, the clay itself is a high quality clay, it doesn't leave any clay taste or crumbs in the flavour, easy to clean, it just gives you the right taste of your flavour.
*Important* this is very suitable for individual use, it's not too small, it's not too big, it's between medium and small, just perfect.
