Yes. I throw each jug, bowl, mug, and plate by hand on the potter's wheel in my studio, then turn, glaze, and fire it myself.
No two pieces are identical. Throwing by hand and firing in the kiln give each piece small differences in size, shape, and glaze. Variations in color, speckling, pooling, and drips are part of the work, not flaws.
Stoneware is clay fired to a high temperature, around 1,240–1,280°C. At that temperature, the clay becomes dense, hard-wearing, and vitrified, making it suitable for everyday use.
