In these videos, Seattle Pottery Supply team potter Sean Tessandori demonstrates how to trim the bottom of a vase and the bottom of a cup after they have been thrown on a pottery wheel. Trimming helps a pot, bowl, mug, or vase sit better on the table by leveling and defining the pot. It also removes excess clay at the bottom so the pot will dry evenly and be less prone to cracking (the bottom is often thicker than the walls, as many potters don't pull all the clay up the walls while throwing). We also feel that trimmed pots feel better in the hand because the physical weight of the vessel matches or is lighted than the visual weight of the piece.
In this video, Sean is using a mug made out of our mid-range translucent porcelain, Seattle Freeze.
