Elements and Performance Criteria

  1. Prepare and maintain resources for glass work.
  2. Explore glass working techniques to plan work.
  3. Realise glass work.

Required Skills

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 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

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 candidates 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 eg literacy and the needs of particular groups eg 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

modelling and carving tools for clay and/or plaster

moulds for hotglass work

piping tools (slip trailer, icing bag, syringe)

pliers (running, grozing, plate)

rulers

slumping moulds.

Equipment may include:

compressor

drill

electric kilns, kiln furniture

engravers

glass cutting machinery (cut-off saw, band saw)

glass cutting table

grinding and polishing equipment (linisher, flatbed grinder, bevel grinder)

light table

PPE, including safety glasses, gloves and wrist gauntlets, dust masks, respirators

programmable kiln controllers

sandblaster

slumping moulds.

Materials may include:

clay

clear and coloured glass suitable for casting (tested compatible frit/cullet, casting glass)

clear and coloured glass suitable for lampworking (tested compatible rods, stringers, sheet glass

clear and coloured sheet glass, including float glass, tested compatible glass

glass colours including paints, stains, enamels and lustres

materials for embedding

plaster

refractory board suitable for making moulds

refractory fillers (sand, silica)

refractory release agents, e.g. graphite, kaolin, alumina, bead release

sculpture wax

texturing materials (whiting, batwash, fabric, natural materials, formed and fired clay).

Glass work may include:

functional forms (platters, bowls, vessels, lighting components)

jewellery and body wear

mural pieces

plaques

sculptural pieces

tiles.

Workplace procedures may relate to such things as:

cost control

process-specific procedures

recycling

reporting

safety

use of materials.

Safety requirements would be in accordance with:

Federal, State and Territory legislation, regulations and standards.

Organisation and maintenance of the work space may relate to:

light

process specific requirements

ventilation

wet and dry areas.

Assessing the capabilities of the techniques, tools and materials may involve:

producing test pieces or samples

systematically testing a range of processes.

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

the subject matter or theme for the glass work, e.g. the body; identity; land and place; political, cultural, social issues; spiritual concerns.

Criteria for the selection of techniques may relate to:

access to materials, tools and equipment for the techniques

consistency with the conceptual vision for the proposed glass work

ease of application of the techniques

personal affinity with the techniques.

Within this unit the candidate would generally extend, build upon and combine a range of techniques which may include:

assemblage

blowing

casting

colouring

etching

fusing

hot forming

lampworking

leadlight/copperfoil

pâté de verre

sand blasting

slumping.
