CUVACD510A
Manage kiln operations

This unit describes the performance outcomes, skills and knowledge required to safely manage the technical operation of a kiln in the context of independent art craft or design practice.

Application

Artists and craftspeople such as ceramicists, glass artists and sculptors apply the skills and knowledge in this unit. They must be able to safely manage the operation of a kiln as part of an independent creative practice. They may also be responsible for the purchase or construction of their own kilns.

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


Prerequisites

Not applicable.

4.2 Set required kiln controls or light kiln according to kiln type being used

4.3 Fire the kiln according to required firing schedule

4.4 Monitor kiln operation and firing process

4.5 Identify and resolve technical problems in the firing process

4.6 Carry out appropriate shut-down procedures

4.7 Liaise with others on technical and creative aspects of firing, including collaboration on specific challenges

5. Address documentation requirements

5.1 Set up a firing log that includes required information

5.2 Record firing details in the log for all work completed

5.3 Review firing logs to inform future work

evaluate the needs of particular work projects to establish kiln and firing requirements

research and evaluate historical and contemporary trends in kiln work

literacy skills to read kiln specifications and requirements

problem-solving skills to identify and resolve:

technical and design issues in kiln work

technical firing issues

numeracy skills to:

estimate costs for kilns and kiln operation

work with numerical features of kilns and firing processes, including temperatures and controls

self-management, planning and organising skills to:

evaluate needs of own practice in relation to kilns

set up a kiln and kiln work space

set up and monitor the firing process

technology skills to safely use technical features of kilns.

Required knowledge

historical, contemporary and emerging trends in kiln types, kiln construction and kiln operation

properties and capabilities of the range of firing materials, tools and equipment, including pyrometric instruments

properties and specification of different kiln types

specific firing processes, including required firing stages, changes to materials, temperature range and timing of each stage of the process

typical problems that occur with kilns and with the firing process and how they may be resolved in the context of relevant materials and art forms

sustainability considerations for kiln work

OHS requirements for the set-up, operation and maintenance of kilns.

Evidence Required

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:

apply safe work practices when using kilns

produce multiple fired craft pieces that are technically sound and free from faults arising from the firing process

prepare own firing schedules

pack and fire kilns independently

apply knowledge of kiln types and kiln operations.

Context of and specific resources for assessment

Assessment must ensure access to:

a workplace or studio for the firing of craft 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 work produced by the candidate in terms of its technical resolution

direct observation of work in progress, including exploration of, and experimentation with, techniques

written and/or oral questioning and discussion to assess knowledge and candidate’s intentions and 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:

CUVCER502A Investigate ceramic materials and processes

CUVGLA502A Investigate glassworking materials and processes.
