Symbolism aside, the gaiwan's round belly form provides a minimal surface area to volume ratio to maximise heat retention, while fanning out at the brim to quicken cooling for easy handling and smooth decantation. This is a classic shape. The lid has a well form dome for trapping air. A lid button has a well formed hollow to keep itself cool enough for resting your finger on it when handling.
