Gnomon Workshop Sculpture with John Brown Volume 4: Molding and Casting the Head (SCU04)

'Molding & Casting the Head' picks up where 'Sculpting the Detailed Character Head' left off. Beginning with the sculpture, this four hour lecture takes the student through preparing the sculpture to be molded, right up to pulling a plaster cast out of the mold. Through a step-by-step process, students will learn a variety of mold making techniques, how to break the sculpture up for individual molding, how to make a flexible silicone Matrix mold, and then on to producing a casting of the sculpture. All while being exposed to the special materials and tricks of this trade. Students will also learn how to avoid the practical pitfalls associated with this kind of work, walking away with a solid foundation for molding & casting their own projects.
