From Clay to Bronze by Tuck Langland (1999)

this studio workbook is devoted to the creation of a large, realistic bronze figure, from initial studies through the complex processes of enlarging, modeling, molding, casting, and finishing. First the book deals with preparing the clay, building the armature, developing the figure study, and enlarging it. Then casting is explored, plaster waste, flexible molds, systems of lost-wax casting, metal chasing, welding, mounting, and patinas. Tips on the maintenance and restoration of bronze sculpture are included.
