Notes de leçon
Experiments answer different questions
- Begin with an intention or an open possibility and inspect what happens. A sample may investigate a mark, edge, material property, arrangement or scale; its purpose matters more than the number of techniques used.
- Creative risk concerns an uncertain artistic result within the taught process. An unexpected result may be useful when observed and evaluated, while dangerous tool use is not an assessment requirement.
Connect the test with an enquiry
Technique relationships and compatibility
- Wax resist can preserve underlying areas against a compatible water-based wash. A painting glaze lets earlier colour show through; scumbling uses a broken relatively opaque layer; sgraffito scratches through one layer to reveal another. Ceramic glazing is a different process.
- Transfers, collagraphs, clay, wire and mixed-media combinations need their specified material system and taught method. Do not infer a universal heat, solvent, firing or inking recipe from a technique name.
Compare original application studies
- The illustrative sampler contrasts diffused wet-on-wet colour, a more defined wet-on-dry edge, dry-brush deposits with gaps and raised impasto. Discuss the visible differences against a chosen intention.
- These are original teaching images, not measured experimental evidence. They do not establish exact paint composition, dilution, drying time or the result of every product on every support.
Compare application effects
Focused comparisons and their limits
- Changing one selected factor while keeping relevant conditions comparable can help investigate its effect. Open-ended trials may change more than one factor, but cannot as readily attribute a result to one cause.
- A single comparison does not guarantee proof: handling, material variation, drying conditions and interactions may still matter. Record relevant influences and choose whether a repeat or further comparison would clarify the result.
An invented focused comparison
Record and evaluate honestly
- Identify the sample, materials, method, intention and relevant conditions, then describe the actual result. Photographs or separately stored samples may support the record where bulky or fragile materials do not belong in a book.
- Explain what the observation suggests, what remains uncertain and what to test next. A disliked result can still be informative; fabricated observations or retrospective claims about an unperformed process misrepresent the evidence.
Make the record useful
Source connections and personal trials
- Investigate a specific feature of a named work using a reliable source. Distinguish a visible effect from an exact historical recipe that the available evidence does not establish.
- A credited study can support a later personal adaptation. Explain what your trial changed and how the effect serves the intention rather than assume unfamiliar tools or more media automatically improve the work.
Avoid an invented historical recipe
Use the approved material and tool system
- Follow the specified material instructions, supervision, process controls and cleanup. Protection or ventilation must suit the actual task; an open window or generic mask is not a complete plan for every spray, solvent or dust.
- Keep creative uncertainty separate from physical hazards. For unfamiliar tools, adhesives, mixed materials or heat processes, seek the taught method rather than improvise a procedure from a short definition.
Creative uncertainty and physical safety
Choose a next decision
- Compare the observation with the intention, then decide whether to repeat, change a condition, explore an alternative or revise the aim. Refinement may simplify the work rather than add layers or detail.
- A small sample has limits at final scale. Record a remaining question about marks, support, assembly or display so the next action follows evidence rather than the cost or novelty of the materials.
