A practical manual on decorating pottery beneath the glaze that combines hands-on techniques, material science, and design guidance. It surveys clay and glaze composition, the chemistry and handling of pigments, surface preparation, brushwork, and firing practices, and presents step-by-step procedures alongside experimental observations and practical recipes developed in collaboration with working potters. The text stresses the importance of drawing and sound decorative principles, warns against amateur overreach, and guides readers from basic materials and processes through application methods and troubleshooting to help learners develop skill by patient practice.
