Unit of competency details

Unit descriptor 

This unit describes the skills and knowledge required to produce glass work through the exploration and application of a range of techniques, tools, equipment and materials. As such the range of techniques could be quite varied and broad in nature. It is a specialisation unit and refers to a specific art form. This work would usually be carried out under limited supervision.

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

Prerequisite units 

It is highly recommended that this unit be assessed in conjunction with the following units:

• CUVCOR03B Develop, refine and communicate concept for own work
• CUVCOR08B Produce drawings to represent and communicate the concept
• CUVCOR12B Review history and theory for application to artistic practice.

Depending on the context, combined assessment and/or training with a range of other units would also be appropriate, e.g.:

• CUVCRS08B Document the work progress
• CUVCRS14B Prepare, store and maintain finished work.

Employability skills 

This unit contains employability skills.

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.

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills :

• literacy skills sufficient to read product safety labels and directions for equipment use
• numeracy skills sufficient to calculate quantities, and firing times.

Required knowledge :

• the physical properties and capabilities of the range of materials, tools and equipment used in glass work
• work space requirements for glass work including ways of organising and maintaining space
• ways of exploring, adapting and combining techniques and materials to achieve different effects in glass work
• general knowledge of the formal elements and principles of design and their specific application to the production of glass work
• cleaning and maintenance techniques for tools and equipment used in glass work
• general knowledge of the historical and theoretical contexts for glass work

• awareness of copyright, moral rights and intellectual property issues
• environmental issues associated with the tools and materials used in glass work
• organisational and legislative occupational health and safety procedures in relation to glass 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.

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

The following evidence is critical to the judgement of competence in this unit:

• production of glass work which demonstrates a command of selected techniques and which is consistent with the conceptual vision
• knowledge of materials and tools and how they are used and extended in glass work.

Context of and specific resources for assessment 

The assessment context must provide for:

• evaluation of visual language and technical execution of work pieces produced by the candidate
• practical demonstration of skills using required tools, equipment and materials to produce multiple pieces of glass work or a single major work.

Method of assessment 

Assessment may incorporate a range of methods to assess performance and the application of essential underpinning knowledge, and might include:

• direct observation of glass work in progress
• questioning and discussion of the candidate's intentions and work outcomes
• verbal and written reports
• review of portfolios of evidence
• third party workplace reports of performance by the candidate.

Assessment methods should closely reflect workplace 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).

Assessment of this unit requires access to the materials, resources and equipment needed to produce glass work.

RANGE STATEMENT 

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised  wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Tools  may include:

• brushes
• cutting aids and guides, including templates, braced squares, grids
• hand glass cutters, including regular glass cutter, circle cutter
• hand polishing pads

Extending capabilities  of techniques refers to:

• exploring the potential of techniques and discovering new ways of using techniques.

The conceptual vision  may be determined by:

• elements and principles of design
• the relationship of the work to a theoretical and historical context
