The ceramic cup is a modern gaiwan modification that fits snugly in the hand. A large volume infuser gives tea leaves enough room to unfurl and release their full flavor. A tight-fitting lid and thick walls keep the heat in as the tea steeps. A handle doesn’t get hot so you can savor your favorite infusion without risk of scalding hands. The cup is covered with crackle glaze that preserves the taste of the brew. It will enhance the future infusions if you use the mug for the same type of tea.
