When there are more than five guests for 濃茶（こいちゃ）, host enters with stacked 茶碗. The one in the inside, holding 茶巾, 茶筅 and 茶杓 is called 主茶碗（おもじゃわん）, and is used for the first guest. The outside one is called 替茶碗（かえじゃわん）, which means alternate bowl.

According to Chanoyu Vocabulary, different kinds of ceramic should be used here; unless it's 島台（しまだい） 茶碗. Alt least one should be 楽, so you can avoid having to carry two 古帛紗.
