About this course

Process and test found materials local to West Dean College, or from your own locality, to produce and understand the fundamentals of how a glaze is made.

Course Description

Explore the possibilities for making glazes from found materials. The aim is to give you the ability to find your own personal glazes from any locality through the practical knowledge gained when we look for and experiment with materials local to the College or those you bring from your own area. You will learn how to procces collected materials.

The emphasis will be on empirical learning. The course will begin with explaining the fundamental materials that make a glaze and test firing them. The results will give a visual understanding of glaze making that will be built on through further experimentation. Most experiments are fired in electric kilns but it is intended to fire the gas kiln in the middle of the week to discern the effects that different kiln atmospheres have on glazes. Some finished work can be fired in both the electric and gas kilns if you bring biscuit-fired ware.

Historically, all glazes were made with locally collected materials. We will:

• Experiment with only using local materials to make glazes

• Mix found and purchased material, as sometimes a necessary ingredient is unavailable locally or too arduous to process!

• Personalise a base glaze with a found material

If you want to make earthenware glazes, then a base earthenware glaze can also be personalised. If you have a favourite glaze that you use, bring some with you for experimenting with.

Collecting and processing materials will form part of the course, although, owing to the natural cycle of plants and the need for them to be thoroughly dried before burning, some preparation may already have been done. Also covered will be: a talk on the tutor's own work practices, including the perils of shells and seaweed; the work of other potters who use natural glazes; question and answer sessions. The week will end with an assessment of the results of glazes, and a discussion on the ways forward for your own work.

Anyone who wants to bring some of their own local materials, like quarry dust, dug clay or plant ashes, and biscuit fired ware of the clay they normally use for experiments, is encouraged to do so. Materials are supplied if it is impractical for you to bring any of your own work or samples. The course will equip you with the skills and knowledge to find your own unique glazes recipes when you return home.

Course Materials

Included

  • Any clay, glaze materials or firing costs as used at the College.

What students need to bring

  • Any personal tools you like to use, such as silicone spoons/scrapers, whisks. (West Dean has a range of studio hand tools including; loop tools, brushes for applying glazes (synthetic/bristle are suitable, not good quality), synthetic sponges, cup measure sets, digital scales, domestic sieves, 60 mesh sieves.)
  • Overall/apron, covered footwear in the studio, plus outdoor clothing and footwear suitable for walking over rough ground when collecting materials.
  • Items listed below would be useful if you wish to bring them:
  • Notebook
  • Biscuit fired test pieces in the clay you normally use. Approx. 50. (A saucer shape approximately 5cm (2 inches) made in any way). As natural glaze tests often run, a saucer shape is necessary to save kiln shelves. It's important that you number and initial test pieces prior to firing.
  • If you wish to bring larger pieces for a final firing, please ensure that these are also bowl/saucer shaped, up to approximately 20cm (8 inches). Please also number and initial.
  • Raw Materials
  • If you have a favourite or abundant plant, please bring a dry sample, or preferably burn it and bring the ash.
  • If you have a local quarry, you could ask them for a sample of fine particles. In the tutor's experience, quarry workers are often interested and helpful but a little bemused by a request for dust.
  • Deposits of fine rock particles or clay are also worth collecting.
  • You are also encouraged to bring any examples of natural glazes you use. Also, if you have a base glaze (plain glaze, purchased or your own recipe) you like using, bring a raw sample to add found materials to (500 ml to 1 litre liquid, or dry equivalent).
  • Approx. 20+ yoghurt pot type containers + lids to enable you to take home left over raw glaze material.

Available to buy

  • Available from shop:
  • Pottery tools, pottery knife.
  • Notebooks, rough paper or sketch pad, and pencil
  • Natural sponge
  • Pencils for marking the base of your pots
