This version first released with CUV11 Visual Arts, Craft and Design Training Package version 1.0

Unit Descriptor

This unit describes the performance outcomes, skills and knowledge required to make and apply a range of glazes to create different aesthetic effects for ceramic items. The practitioner uses a variety of techniques to both make and test different types of glazes, including the development of original glaze recipes. The unit requires a sound knowledge of glaze science.

Application of the Unit

Ceramicists apply the skills and knowledge in this unit.

At this level, work is carried out independently with mentoring and guidance as required.

Licensing/Regulatory Information

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement.

Pre-Requisites

Not applicable.

Employability Skills Information

This unit contains employability skills.

Elements and Performance Criteria Pre-Content

Element 

Performance Criteria 

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

  • OHS requirements for glaze work.

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Evidence of the ability to:

  • produce a body of ceramic work that shows command of selected advanced glazing methodologies, techniques and tools
  • make and test original glazes for own work
  • evolve and refine glaze work through a demonstrated process of experimentation and problem solving
  • maintain accurate records of glaze work
  • research glaze practice and history as a source of ideas for own work.

Context of and specific resources for assessment 

Assessment must ensure access to:

  • a safe ceramics work space
  • ceramic materials, tools and equipment for glazing work.

Method of assessment 

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

  • evaluation of glazing skills within a body of work produced by the candidate
  • evaluation of processes used by the candidate to evolve and refine glazing technique
  • questioning and discussion about candidate s intentions and the work outcome
  • review of portfolios of evidence
  • review of third-party reports from experienced practitioners.

Assessment methods should closely reflect work place demands (e.g. literacy) and the needs of particular groups (e.g. people with disabilities, and people who may have literacy or numeracy difficulties, such as speakers of languages other than English, remote communities and those with interrupted schooling).

Guidance information for assessment 

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

  • CUVACD510A Manage kiln operations.
