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.

Exquisite Corpse: Artifacts

hildesheim_corpse2010_72Exquisite corpse or Cadavre exquis is traditionally a drawing technique where a bank of words or images are collected, and assembled to create a finished composition.  This project explores this surrealist idea in an assemblage of components to create an “Exquisite corpse” sculptural artifact.

Mission: (Project Description)

 In this project, the student is asked to create five artifacts from the inventory of objects created from previous mold-making assignments. Students are allowed to melt, cut, deconstruct, and transform existing objects and reassemble them into unique sculptural forms/figures. The final form may be prepared as if to be cast in metal using the gating method for the traditional investment lost wax method. Other materials may be added. Attention should be given to how additional materials are fastened to the wax objects. Note whether objects will remain as original material or be cast pin metal.

Hot Metal Casting: Sand Molds

06_Wheatley_Toxic Swimmer_2014

Mission: (Project Description)

Learn the process of developing a metal casting using a two-part sand resin bond mold. The first part of the project will be to create a pattern using a variety of methods and materials. Mixing sand and resins the student will create a mold. The mold will be used to create a void to pour metal. The metal sculpture will then be finished accordingly. The student will be graded by keeping a schedule with the processes of the assignment as well as the finished form. Keep up, so you do not fall behind.

Scratch Block Molds – Casting Forms in High Relief

Sheen Square72In this project the student will learn the process of developing a “Relief” metal casting using a Scratch Block, a sand block bonded with resin, to create a negative or inverse of a final relief sculpture. Metal will be poured into the scratch block to create the finished form. The metal relief sculpture will be finished, and chased using metal working tools. Then dioxide and wax will be applied to the surface. And finally, a strategy must be developed to display the relief form.

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.
