When you see the vivid colours of an Elizabeth Frink bronze head or the delicate lace texture of Hew Lockes Queen Victoria sculpture, do you wonder how those complex surfaces were created from raw billets of bronze? In this all-levels course, you will learn the step-by-step processes used to elevate rough castings into beautiful works of art with detailed surfaces, consistent textures and rich colours.
Beginning with a bronze casting demonstration, this course will cover the complete process from casting to a finished sculpture. Chasing and finishing techniques, including retexturing, fixing any imperfections and making your own custom texturing and chasing tools will be covered.
Patination is the colouring and treatment of the surface of metal using chemicals, heat and time. This mimics the natural reactions that occur when the copper in the bronze alloy comes into contact with the atmosphere over centuries. This results in the deep greens, browns, black and blues which bronze works are known for. Traditional and contemporary patination practices will be covered in detail, touching on atmospheric and burial patinas but with a focus on hot application patinas. You can expect to produce a finished, patinated bronze work by the end of the course.
Anyone who has previously completed the Sculpture Skills: Waxworking for Metal Casting course will have their wax work cast during the first evening demonstration. Anyone who has not attended this optional precursor course will be provided with an alternative casting to work with. Please message the tutor ahead of the class for details.
Overview:
On the first evening there will be a welcome and an overview of the course including a bronze casting demonstration.
Day 1
In the morning, there will be a discussion of processes and health and safety considerations for the course. You will learn about divesting moulds, and there will be demonstrations of how to remove mould material. You will learn about removal systems and there will be demonstrations of best practices for using angle grinders, die grinders, as well as other tools.
In the afternoon, there will be a shot blasting demonstration, and also a demonstration on best practice for chasing and retexturing, including removing flashing, blending back any remaining sprues and making custom texturing stamps.
Day 2
In the morning there will be a patina demonstration, including an overview of the preparation of sculptures, chemical recipes, application techniques and use of heat and torches. Patina samples and practice pieces will be provided.
You will finish the metalwork for your pieces and shot blast works ready for patination. The aim is to have work fettled and ready for patination
In the afternoon, you will practise patination techniques and begin patinating your work.
Day 3
In the morning, there will be a waxing and polishing demonstration, including best practices for sealing and preserving colour and surface detail. In the afternoon, you will complete patination of your pieces, including waxing and buffing.
The aim will be for you to complete a bronze sculpture, including metalwork and patination to a professional standard.
