Hot Metal Casting: Lost Wax Process

Perry_Beauty is in the Eye of the Beholder_2008Mission: (Project Description)

Hollow lost wax casting method: A unique wax pattern will be developed using plaster and rubber molds. The wax pattern will be taken through the “Lost Wax Process” to create a unique bronze or aluminum sculpture with a patina or alternative finishing method. Individual students have a choice to cast a wax form presented from a previous course or to create a new hollow casting for this project. A hollow lost wax casting method is the only technical criteria. If a new casting is to be produced, you are encouraged to create a composition and concept that pushes the envelope of this level course.

This project will challenge and further introduce the student to the processes of casting metal. A traditional investment material of plaster, silica sand and silica flour will be used for this project. The student should show an understanding of the methods listed below. A metal form will be cast and finished by the student.

Sculpting the Human Head/Body

Fickle_72Prologue:

The bust has been used for centuries to honor, memorialize, characterize, and distinguish identities of culture. As a social political tool, as many forms of art have been and will be, the face and bust have been used to provide an instrument of social control and propaganda. For ourselves and prosperity art through human form has been a link to the identities of personalities of the past. History, mythology, and other stories are hinted at, and revealed by these simple yet complex forms. We have a compulsive draw towards the replication of identity through various mediums, to empower a material to conjure a sense of preservation.

Mold Making: Encapsulated Rubber Molds

ES_long72

Mission: (Project Description)

In this project, the student will be introduced to “Encapsulated Mold-making”. Rubber will be used as an interior jacket to collect surface and surface detail. A plaster exterior mother mold will be used to establish a structure for the flexible mold. Rubber is an elastic material that can pick up very minute detail. Its flexible quality allows it to be pulled and stretched to cast challenging objects that can not be cast from a more rigid material. The mold material can be used numerous times with many different materials, respectively.
