This cup is in excellent condition with no chips or cracks. In the base of the cup and in one place on the outside wall (pictured) there are two stains which seem to come from iron during the firing. These are under the glaze and can't be cleaned. In the base of the cup there is a place where the glaze has split during firing, but this doesn't extend below the glaze.
As with all antiques of this age, this was handmade and woodfired. Please expect some character as is appropriate for pieces of this age.
