Elements and Performance Criteria

This competency unit includes products, such as:
sanitary ware
bathroom fittings
insulators
cups, saucers
tiles
bricks

This competency unit includes equipment, such as:
belt feed hopper
dipping equipment
hand spray equipment
screen printers
silk screens
vibrating hoppers

This competency unit includes processes, such as:
decorating
dry glaze/material
glaze fault repair
manual dip
manual spray
oversand spraying
reglaze (repaired products)
silk screen printing
waterfall/flinger/bell
wet glaze/material

This competency unit includes materials, such as:
artwork
colours
cover coat
dry glaze dusts
frits
glazed products
liquid glaze
paints
sand
slurry.
This unit was developed for larger production contexts but it may also be relevant to craft practitioners producing ceramic work.

It does NOT include:
product forming and drying
product firing
setting up automated glazing equipment.

Typical problems include:
glaze application faults (eg, non-adherence or runs)
applicator equipment problems
product surface unsuitable for glaze application
glaze consistency
contamination.
All operations are performed to procedures.

OHS
All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence.

Assessment context and methods
Assessment for this unit of competency will be on an operating plant. The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency. Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.
Simulation or case study/scenarios may be required to allow for timely assessment of parts of this competency unit (eg, those parts of element 4 referring to glaze repair techniques). Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. Simulations may also include the use of case studies/scenarios and role plays.

Critical aspects

Competence must be demonstrated in the ability to recognise situations requiring action and then in implementing appropriate corrective action. Consistent performance should be demonstrated. In particular look to see that:

glaze application is within requirements
equipment is used as required
glazing faults are recognised and categorised correctly.
These aspects may be best assessed using a range of scenarios/case studies/what ifs as the stimulus, with a walk-through forming part of the response. The assessment activities should include responding to a range of problems.

Resource implications
Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations. A bank of scenarios/case studies/what ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions.

Other assessment advice
This unit has no prerequisites.
Individual enterprises may choose to add prerequisites and corequisites relevant to their processes.

Essential knowledge
Knowledge and understanding of the glazing and decorating equipment sufficient to recognise conditions which will lead to out of specification product.
Knowledge of the enterprise's

Competence includes the ability to:


apply and/or describe:

glaze composition and function
decal construction and application techniques
glaze application techniques (including hand dipping and spraying)

distinguish between causes of problems such as:

product surface condition
equipment problems
glaze properties
as is relevant to the practical operation of the equipment.
