Foundations of Ceramics and Pottery: Clay Science, Forming Techniques, and the Firing Process

Ceramics is one of humanity's oldest material practices, and yet every object fired in a kiln today engages the same fundamental principles: the plasticity of clay, the transformation of mineral oxides into color and surface at high temperature, and the irreversible change that heat makes to the formed material. Understanding those principles — not just the procedures — is what separates a practitioner who can adapt and problem-solve from one who follows recipes without comprehension. This foundational course builds that understanding. By the end of this course you will be able to describe the properties of different clay bodies and explain how those properties affect forming, drying, and firing behavior, compare the primary hand-building and wheel-throwing forming methods and identify when each is appropriate, explain the basic chemistry of glaze materials and how fired color is produced, and describe the stages and effects of kiln firing from bisque through glaze firing temperatures. What you will learn: - Clay body types: earthenware, stoneware, and porcelain — composition, working properties, and fired characteristics - Particle size, plasticity, and moisture content: why clay behaves the way it does - Hand-building methods: pinch, coil, and slab construction — structural logic and limitations - Wheel throwing fundamentals: centering, opening, pulling walls, and the physics of symmetrical rotation - Drying, leather-hard stage, bone-dry: why controlled drying matters and what goes wrong when it doesn't - Glaze chemistry basics: flux, silica, and alumina — how the unity molecular formula works conceptually - Colorants and surface effects: metal oxides, opacifiers, and the effect of atmosphere (oxidation vs. reduction) - Kiln types and firing: electric, gas, and wood kilns — temperature curves, cone ratings, and firing effects The course is organized across five units progressing from clay science through forming techniques, drying, surface treatment, and firing. Each unit provides explanatory readings, illustrated case examples showing how concepts apply to real forming and firing decisions, and structured reflection prompts. Self-assessment exercises at the end of each unit test conceptual understanding before moving to the next stage. This course is educational; hands-on ceramics work, kiln operation, and the use of raw glaze materials require supervised training in a properly equipped studio. Kiln operation carries safety risks and should only be undertaken under appropriate instruction and with proper safety precautions. This course is designed for aspiring ceramicists, art students, and craft enthusiasts who want a rigorous conceptual foundation before or alongside hands-on studio practice. It is suitable for those new to ceramics. No prior background in chemistry or art is required.
