The other difference is its shape. The side body of Big Edo style tea bowls display a steeper incline than Edo style bowls. This effect makes this bowl less subtle than Edo style bowls. Consequently, when one drinks from a Big Edo bowl the tea embraces the mouth less gracefully and slightly more forcefully due to this difference.
This bowl pictured is a wonderful Big Edo style piece by ceramic master Jung Jum Gyo.
