This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
Learners who demonstrate competence as described in the outcomes of this unit standard will be able to apply relevant technology when producing and conditioning molten glass.

This is achieved by:
  • Describing the melting process.
  • Describing and applying technology used in the glass melting process.
  • Describing and applying safety, health environmental and quality practices used in the glass industry.
  • Describe economic considerations applicable in the glass melting process. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Learners accessing this unit standard will have demonstrated competence regarding:
  • Health, safety, environmental and quality issues and technology relevant to processing (chemical) materials
  • The preparation of batches of material for further processing or the equitant expertise
  • The application of process chemistry and related technology in an industrial context
    Where learners do not have the relevant expertise, appropriate adjustments must be made to the learning programme. 

  • UNIT STANDARD RANGE 
    These are stated with the relevant specific outcomes above. 

    Specific Outcomes and Assessment Criteria: 

    SPECIFIC OUTCOME 1 
    Describe the glass melting process. 
    OUTCOME RANGE 
    Activities include molten glass production, forming (flat, container, fibre) cold end processes (cutting, quality checking, packaging, manufacturing of specific products
    Use of glass includes types of glass and their application in architectural, container, automotive, insulation fibre structures.
    Alternative materials include metal & plastic
    Recycling and destruction includes reuse, re-melting, the lack of natural decomposition of glass, shortages of glass grade raw materials and energy requirements for glass manufacture. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    1. Describe the glass melting process with reference to the furnace and related infrastructure as well as the composition & properties of glass. 

    ASSESSMENT CRITERION 2 
    2. Explain the inter dependence of down stream activities in terms of the technical processes and activities carried in the melting process. 

    ASSESSMENT CRITERION 3 
    3. Describe glass products in terms of their use, recycling & destruction and alternative products/materials of construction. 

    SPECIFIC OUTCOME 2 
    Describe and apply technology used in glass melting process. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    1. Describe the physical and chemical properties of glass, and the components of glass, with reference to quantitative values/composition. 

    ASSESSMENT CRITERION 2 
    2. Carry out calculations used to control a glass manufacturing operation using known formulae/calculation procedures. 
    ASSESSMENT CRITERION RANGE 
    The range of calculations is indicated by the following examples:

    Determination of power consumption and energy & heat balances and thermal history across a melting furnace
    Determination of raw material required and available and mass balances needed to ensure production over a specified period.
    Determination of productivity across an melting operation (melting rates, power utilization, supply and demand, relationship between top heat and boost ?).
    Describe the implications of different amounts of contaminants on the glass and estimate the amount of glass affected by a contaminant.
    Expansion & heating rates and consequences on the furnace.
    Melting rates and the consequences of non-conformance with instructions.
     

    SPECIFIC OUTCOME 3 
    Describe and apply safety, health, environmental and quality practices. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    1. Describe the industry safety and health practices in terms of a recognised system within formal industry with reference to general principles applicable to safety, health, environment & quality (SHEQ). 

    ASSESSMENT CRITERION 2 
    2. Identify and explain the steps of the SHEQ system(s) used at the learner`s place of work and the activities of people in key positions 

    ASSESSMENT CRITERION 3 
    3. Carry out SHEQ activities in the learner`s own working context in accordance with the site specific systems. 

    ASSESSMENT CRITERION 4 
    4. Compare the learner`s activities / to the requirements of the system and principles underpinning the system with reference to adequate conformance to standards/instructions, productivity and constraints imposed by society. 
    ASSESSMENT CRITERION RANGE 
    Examples of systems are ISO 9000 & ISO 14000 and Good Manufacturing Practice, HAZOP
    Society includes employer, suppliers, customers internal & end users and environmentalists.
     

    SPECIFIC OUTCOME 4 
    Describe economic considerations applicable in the glass melting. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    1. Explain the concept of `adding value` with reference to glass manufacturing, distribution, use and the cost of melting with reference to a simple balance or budget sheet/table. 

    ASSESSMENT CRITERION 2 
    2. Explain the relationship between profit and loss of the operation with reference to the budget and actual costs, opportunities for improvement of profitability and productivity, down stream customer service and company performance where the learning takes place. 
    ASSESSMENT CRITERION RANGE 
    The documents used are limited to simple tables reflecting budget items and costs
    Opportunities for improvement include items that are determined by issues such as efficiency of the process, wastage of materials, recycling and achievement of realistic production targets
    Differentiation between issues within and beyond (such as input costs, selling costs and simple cash flow) the learner`s and production personnel`s control should be made.
     


    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
