List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Develop ideas for glazing ceramic items | 1.1 Evaluate potential for new and original approaches to own glazed ceramic work, including use of original glazes 1.2 Research glazing ideas from historical and contemporary references 1.3 Research, adapt and use relevant ideas and approaches from other practitioners and comply with intellectual property requirements 1.4 Refine and confirm ideas through research, experimentation and testing |
2. Modify and test existing glaze recipes | 2.1 Investigate and respond to specific safety and sustainability issues for glaze work 2.2 Modify and test existing glaze recipes on various clay bodies and in various kiln firing conditions 2.3 Achieve different effects through exploration and experimentation with a broad range of advanced glazing techniques, equipment and tools 2.4 Label and store glazes safely |
3. Formulate original glaze recipes | 3.1 Analyse glaze science and chemistry to inform ideas for original glaze recipes 3.2 Research how raw ingredients and formulas achieve different effects 3.3 Formulate own glaze recipes that aim to achieve predictable fired results 3.4 Test original glazes on various clay bodies and in various kiln firing conditions, and record data |
4. Create a body of glazed work | 4.1 Select and use recipes and glaze application techniques according to required effect and modify application as required 4.2 Decorate surfaces with glaze using techniques and tools selected from own experimentation 4.3 Evaluate and respond to potential for changes in application methods 4.4 Fire the glazed form at the appropriate temperature and kiln atmosphere 4.5 Modify glazes to correct faults and technical problems 4.6 Maintain accurate records and data for glazing and firing processes |
5. Evaluate glaze work | 5.1 Evaluate glaze work from an aesthetic and functional perspective 5.2 Evaluate development of own technique for glazed ceramic work with others and seek feedback 5.3 Evaluate particular ways that experimentation with different techniques has informed own artwork 5.4 Identify ways to further develop glazing techniques as part of professional ceramics practice and build ideas into future work |
Evidence of the ability to:
research an extensive range of historical and contemporary glazed ceramic work and techniques to inform own designs
refine glazing technique through a process of thorough experimentation and problem solving to create a coherent body of glazed ceramic work which:
shows a command of chosen advanced glazing methodologies, techniques and tools
demonstrates the development and testing of both existing glaze recipes and own formulated recipes
supports own ideas for work.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

colouring oxides
glazes
slips and engobes
describe the effects of heat on glaze
describe ways to identify and correct glaze faults
explain the properties, characteristics and the effects on glazes for:
commercial clay
naturally occurring clay
materials used in clay bodies
describe the drying characteristics of clay body and dried sample at various firing stages
explain the features of a range of advanced glazing techniques and how they work to achieve different decorative effects in glazed ceramic work
summarise techniques used to decorate green ware and fired ware surfaces
outline the benefits and disadvantages of in-glaze, on-glaze and under-glaze decoration
explain key safety requirements for ceramic work.
