Terms and Conditions of Enrolment

Course Overview

Extend your skills in mould-making and casting for sculpture as you learn how to create a silicone and plaster mould from your own clay sculpture. Claire Tennant leads you through the step-by-step processes of working with terracotta to a create a sculpture,  making a reusable silicone mould, and  casting the final product . You will also learn about detailing, finishing and patination techniques. Claire will show you how to make a apply silicone and plaster to create a mould of your clay sculpture; take a positive casting in plaster from the mould, and apply various professional finishing and patination techniques. Discover the fundamentals of silicone application, how to create moulds for difficult sculptural forms; the challenges involved in using the medium of plaster; and casting techniques as well as common casting problems.

Students are encouraged to look at a range of sculptural finishes and have some basic ideas about what they would like to create prior to beginning the course. Keep in mind that the sculpting element of the course is only 1 out of the 5 days, so highly detailed work may not be possible. The finished sculpture will be approximately 30x30x30 cm and is created in terracotta clay.

It’s recommended to have 2-3 loose ideas for a piece than be cemented into one idea, as there are limitations with the time frame and appropriateness of some forms.

As a general rule, bulky solid forms (like a portrait bust) will be easier to achieve in the time than, for instance, a figure with long thin arms and legs, as we will not be working with structural armatures.

Open to students of all levels of experience.
