This is a handmade white gaiwan with a chinese landscape as motif. The gaiwan is made of Chinese porcelain. A gaiwan is a type of Chinese tea cup with lid, and is a popular way to prepare tea in China. You use the lid as a strainer and move the tea, put on the lid, and by a smaller gap, pour out the tea.
Gaiwan is often used as a teapot to pour into a pitcher, but you can also drink directly from a gaiwan like a teacup, where the lid is used to move the tea aside.
Dimensions: Gaiwan is approximately 10 cm high, 10 cm wide, with a volume of 2 dl.
