A cup is a small sculpture that has to work in the hand. Its handle changes balance, grip and the way the rim meets the drinker. Those decisions become clear through repeated making and testing.
Glaze colour cannot be understood from a screen alone. Shape, light and the fired surface all influence what we see. A good colour study makes those differences visible rather than trying to hide them.
Handmade ceramics are made to be encountered, but every piece has its own use and care requirements. Begin with the maker’s instructions rather than assuming that all fired clay behaves in the same way.
