Here is a little yixing tea jar. It is about 2.5" tall and has fairly thick walls. There is a tree on one side, and some "seal script" characters on the other side (my guess). One charater (on right) resembles "cha" to my untrained eye.
Most likely, the jar was cast and the tree and other details were incised or sharpened by hand. The lions have a hole sideways through the mouth, as well as one where the mouth is. Perhaps they were for a handle.
I'd guess it is somewhere between 100 and 150 years old, dating from the rule of Empress Dowager Cixi. Of course, that is completely irrelevant, but I can pretend it adds fantasticly to the value.
It would be wonderful to have a series of jars like this, ranging from a daily use size like this, to big containers that could hold seven cakes.
