New online glaze course: How Glazes Work

colour blend

Do you want to learn about glaze chemistry but don’t have the time to spend weeks on a course?

I have been working on a new online course on how to make your own glaze and what each material contributes. Learn how to add colouring oxides and combine different oxides in a colour blend. I’ve carefully constructed, edited and condensed quite a lot of content into a short glaze course. By the time you finish, you will have a good understanding of the principles of making a glaze and, knowing what each ingredient does, you will have some confidence when it comes to adjusting your glazes. You will also have gone through some key practical steps in making glazes and will have seen some ‘good practice’ which will ensure you get reliable, repeatable results.

What you will learn:

Glaze chemistry

1. The three main components of a glaze and what each material contributes to the glaze.

2. The difference between a glaze recipe and molecular formula and how it relates to glaze stability.

3. Glossy and matt glazes, adjusting glazes and correcting defects.

4. Adding colour, in the form of oxides and stains. Health and safety.

Practical session on how to make your own glaze and add colouring oxides.

Materials and preparation

You will need to make 15 test tiles, rectangular clay slabs around 6x4x0.5cm. You will need to fire the test tiles in a kiln. I prefer stoneware temperature 1250°C, cone 8, but you can use higher or lower firing temperatures and choose your own glaze base.

Who is the course for?

Beginners and intermediate potters will find this course useful, especially if you want to learn how to make your own glazes and understand what each material contributes.

Who is teaching the course?

Linda Bloomfield trained as a materials scientist and worked at Imperial College in London before having children and becoming a potter. She has written six books on glazes and tableware and teaches workshops on understanding glazes. The online course covers the same content as her weekend workshop.

How long does the course take?

The theory video takes half an hour to watch and is divided into four sections.

The practical session takes half an hour to watch and around two hours to complete the glaze tests yourself.

How much does it cost?

Special introductory offer £60

Glaze course dates for Spring 2016

I will be teaching several glaze courses in the Spring, both at West Dean College and Morley College in London.

The West Dean course has up to 10 students and costs £466 for four and a half days. West Dean is a beautiful old stately home and gardens near Chichester in West Sussex. It is a residential course unless you live nearby and can travel in each day. The accommodation and food is excellent and you can continue to work in the studio in the evenings if you like.

The Morley College course is new and costs £125 for 5x 3hr or 3x 6hr sessions. Morley College is in Lambeth, London, on Westminster Bridge Road near Waterloo or Lambeth North tube station.

The dates are

19 February -18 March 2016, Fridays 6-9pm for five weeks at the Morley College: Glaze making and understanding materials.

17-21 April, Sunday to Thursday, four and a half day short course at West Dean College: Understanding Colour in Glazes.

23 April -7 May, Saturdays 10am-4pm for three weeks at the Morley College: Glaze making and understanding materials.

Phew, that’s quite a lot of teaching for me. If you can’t come on a course, you can look in one of my books instead.
