Using a handmade object feels so good. Who could go back to drinking out of a mass produced mug once they have used one made by hand? With that in mind, I love adding details that make my pottery fit the human hand. A thumb indent and a folded down lip are simple alterations to a thrown form, but to me they give the piece the feeling that it was meant to be used.
All my functional pots start out with an initial firing called a bisque, then they are finished with a glaze firing that is either cone 6 electric oxidation or cone 10 gas reduction.
