Casting & Sculpture in Jesmonite (Sat & Sun, 26 – 27 Feb 2022)

This two day course is an introduction to working with Jesmonite.

Jesmonite can be used to replicate the appearance and texture of any surface finish, and even the finest of detail. It can mimic the appearance of materials such as stone, wood, leather and fabric. It is strong and durable, can be pigmented to any colour and used to create decorative surface effects.

It is often used as lightweight alternative to stone and concrete. It has become an increasingly popular material widely used by artists, designers and prop-makers.

Jesmonite is a brand name for a group of products that have a gypsum base and a water based acrylic resin making it kinder to the environment than other resins.

This two day course will explore the different applications of Jesmonite . You will have the opportunity to work hands on, constructing geometric and curved forms, creating decorative effects using pigment, and you will learn how to replicate other materials and textures using Jesmonite.

Day 1

Day 2
