Casting in Concrete & Plaster

In this 2 day workshop, students will be constructing and casting shapes, and are encouraged to experiment with different finishes.

Participants will have the opportunity to think through making and explore material qualities hands-on.

This workshop is designed to both introduce participants to the methods and processes involved in casting and moulding in plaster and concrete, whilst also encouraging the exploration of experimental mould construction and the possibilities of negative space (the mould) and positive space (the cast).

Day 1 – Methods and Experimentation

Day one will introduce the two main casting materials that we will be using through several quick moulding and casting exercises including making relief panels from clay and sketch moulds from plastic sheet/cardboard. We will follow this up by exploring colouring through making bowl forms to also understand reinforcement of plaster to enable it be cast hollow. We will end the day with by discussing possible personal projects for the following day and other techniques that participants might wish to see demonstrated.

Day 2 – Personal Project and Extrapolation

The second day is an open-ended exploration of the techniques learnt on day one through the development of a small personal project. The tutor will be on hand to assist and go over techniques explored on the first day and offer advice and possible routes for development. There will also be small demonstrations of various forms of finishing plaster and concrete and discussions focused on where best to use each material and alternative materials and methods.

Please feel free to bring material to experiment with for mould making and casting into.

Please note there will be a 1 hour lunch break each day (lunch not provided).

Basic materials are all included.

Open to all levels including beginners.

Health and Safety briefing will be given.
