Robert English gave an interesting presentation on sculpture.
Robert talked about how foundries use casting wax to make a mold of the clay sculpture to cast it in bronze.
Robert pointed out how important a sturdy armature is for a clay sculpture.
Robert talked at length about how to use rulers to help with calculations to scale something in a drawing up or down, & how that applies to all art forms, not just sculpture.
Robert also discussed the importance of using calipers for helping to scale elements of a picture or sculpture.
Robert gave out handouts that included a drawing of an average-sized horse and an average-sized human, with the proportions mapped out. He discussed how these measurements & proportions are good starting points that can easily be modified to fit a specific horse or person.
