Study the impact of heat on individual or collections of materials used in the production of ceramic glazes.

Studio ceramic practitioners are challenged with a need to find an appropriate finishing process for their work. This inevitably means the application of a glaze or glazes. These glazes start their life as collections of materials either dug from the earth’s surface or refined in industrial processes. They are applied as powder to the surface of clay objects then fired in a kiln to temperatures up to 1300deg.C.
This course unveils the secrets of what happens during the transformational process of firing. The study of the simple chemistry of materials and the impact of heat opens up possibilities of manipulation and control leading ultimately to the design of glazes for specific needs.

Entry requirements
  • Open entry but you must have access to a PC, the internet and a mid-high fire ceramic kiln. 
You will study 

During the first stage, the emphasis is on the basic chemistry of raw materials and their firing. The second stage focuses on patterns in the chemistry of well-known historical glaze types and you will also have an opportunity to research finishing processes which interest you. Upon successful completion of the course, you will receive a Certificate of Achievement. 

Tutor

Lawrence Ewing has been engaged in ceramics for over 40 years. In 1986, he became a staff member at the Dunedin School of Art where he was appointed to teach all aspects of ceramics full-time.

In the early stage of his time at Otago Polytechnic, Lawrence became interested in glaze technology. He designed and implemented a computer programme called "Matrix", which was initially aimed at assisting ceramics students in their glaze work. Over the last 20 years this software has grown to become one of the leading glaze software packages in the world. It is now used by individual potters and schools internationally.

Lawrence is also a Life Member of NZ Potters (Inc.) and has been the web manager for nzpotters.com for many years. He is highly-respected internationally in the field of glaze technology and continues to develop the Matrix software which continues to be used as a teaching tool in the glaze courses for which he is responsible.
