The lip of a glass is the inverted pouring projection (like the lower part of a bird's beak.) on the rim of a jug, pitcher, or saucer. They are made in a variety shapes and styles.
A lip of a particular piece can be formed in different ways. A hot lip piece is finished when the glass is still hot and before it is put in the annealer. A cold lip piece is finished by a grinding method when the glass has cooled.
