2  How do artists choose the material they will use for their sculpture?  How does a sculptor achieve a permanent artwork in materials such as bronze, resins, cements or plaster?  How does interpretation play a part in sculpture?

3  Molding… is the process of securing an impression and molds (hollow forms) provide the method for materials to take on and retain their shape.

5  Is a hollow, negative form into which a malleable or liquid substance is pressed or poured  Create one from just about any material…wood, clay, stone.  The mold must not stick to the final substance you choose to put into it.  Plaster is the primary material used for molds.

6 Hard Molds…  Usually made of plaster, but also fiberglass, metal, epoxy and wood.  Piece molds – o divided into sections for easy assembly and removal of cast object o is a reusable mold.  Waste molds – o one time use  Press molds – o Known as slump molds, pliable material is pressed in or on the surface o Reusable with limited  Hump molds – o Known as drape molds, used when working on the outside of a form Flexible Molds…  Materials include latex, polyurethanes and silicones  Used because the mold is flexible and can stretch over, around or be peeled away from the surface

7  Primary for modeling, casting, carving and construction materials  Is found as a gypsum or as an alabaster, is refined into a powder and heated to standards for the sculptural setting.  White molding plaster, casting plaster and art plaster are recommended.  Causes heat to build up in the setting process so in liquid form, should not be applied to the skin.  Less water creates a stronger mix, but reduces the work time.  Too much water weakens the plaster virtually unusable.  Cold water retards set time; Hot speeds up the process  Always add plaster to water, never water to plaster.  Sift plaster into water slowly; mixture must be thoroughly blended

8  Liquid- pour, brush, thrown, drip  Putty- thicker mix, troweled or scooped into mold  Rigid- slightly set, and frail, but can be trimmed  Set- heat build up as plaster hardens  Cure- once plaster sets until it cures  Dry- plaster is brittle, but strong

9  Draft/ taper mold enables the mold to be released  Undercuts obstruct the removal of the mold

10  creating a mold from a live model…  3 main materials o plaster gauze – the easiest method of molding bandages harden within 10-15 min remember the release agent!!!! (petroleum jelly) o alginate – expensive material used by dentist for tooth impressions o liquid plaster – most available material, but requires more preparation in order to avoid entrapment of the model benefit – produces a rigid, reusable mold of accuracy an detail

11 1924-2000, after NY University of Education, he purchased a chicken farm to make a living, but ended up a teacher of English and Art in a local high school… His chicken coop was transformed into his studio where he played with crude plaster, wire and wood armatures. His work evolved into the use of a simple technique to capture that others overlooked as a “finished” product. He froze the figures forever, trapped in time. “I love to deal with abstraction. I love to probe and examine, but I feel that it has to be rooted in reality.”

12  cut strips and place by pairs so that 2 can be dampened at the same time  obtain warm water, a tray, a towel and a hair covering (bandana, shower cap…etc)  hold by an end and quickly pull through the warm water o squeegee through your fingers to remove excess water and mix plaster in the gauze  apply to the face or hand o smooth plaster with other pieces  make sure all areas are covered!!!  blot face or hand with paper towels to remove excess water and quicken drying time  allow to cure/ harden before removing from the face or hand o then allow to dry fully
