About this course

Create a transferable design and carve a C eltic knot in stone. You will make a Celtic knot initially with rope then a transferable drawing. You will explore the relationships between the weaving and layering of forms and become familiar with techniques to carve a Celtic design into stone.

Course Description

The aim of this course is to inspire you and provide you with the basic skills to design and carve a Celtic knot in stone. To achieve this, you are invited to explore the space between two and three-dimensions using a range of processes, materials, tools and techniques.

After an introduction to low relief in general and the history and significance of Celtic knots, you are invited to explore Celtic knots using rope and, through drawing, create a Celtic knot to investigate the qualities and dynamics of this fascinating form.

You will draw a template on paper, which you will then transfer onto a piece of limestone. The template is a guide to help your orientation as you start carving the outline of this design.

You will start looking at perspective through layering of woven elements as you start transferring and carving your Celtic knot. The predominant element is a regular weave that you integrate into this durable material.

Before you start carving your design, your tutor will introduce and demonstrate to you the tools and basic stone carving techniques, so that you feel ready to put a chisel on your stone tile and carve. The carving demonstration includes:

What are the characteristics of a reductive process?

Which chisel to choose and why

How to create an even surface

Cutting of a clean edge and how to create layers in your carving

How can a woven pattern be transferred into stone?

Once your relief is carved, your tutor will share with you how you can polish aspects of your shapes and use surface texture if you want some forms to stand out.

By the end of this course, you will be able to create your own Celtic knot design through the drawing principles demonstrated, and you will be familiar with techniques applied to carve a low relief woven pattern in stone.

A list of stone and tool suppliers will be available to all students at the end of this course.
