No difference in how you carry it etc, versus a standard ceramic Katakuchi mizutsugi.
For pouring, don’t put your thumb on top. “The rim is a lot deeper than the ceramic mizutsugi, so it won’t fall off.” I also remember Suzuki-sensei saying that it doesn’t rattle like ceramic, so you don’t need to hold it down.
Also, he can’t remember: was ceramic mizutsugi created by Ennosai, or Tantansai? We think Tantansai.
