Plan Sample Matrix
2 hoursDesign grid of species × mordant × modifier combinations on standardized fiber squares.
Learn color chart creation from scratch with a clear step-by-step workflow, recommended tools, safety guidelines, and expert tips.
Design grid of species × mordant × modifier combinations on standardized fiber squares.
Execute each combination with recorded weights, times, and pH; label immediately with codes.
Sew or glue samples to card, write species, mordant, modifier, and liquor ratio for each.
Loading your checklist…
Same scour, mordant batch, and water source across all samples for valid comparison.
Code format: species abbreviation-mordant-modifier (e.g. PH-alum-none).
Typical matrix dimensions.
| Axis | Options | Count |
|---|---|---|
| Rows | Species | 5–10 |
| Cols | Mordants | 3–4 |
| Sheets | Modifiers | 2+ |
Many simultaneous hot pots — organize workspace to prevent mix-ups.
Wet samples look different — mislabeling ruins weeks of work.
Matrix with iron and copper — cross-contamination changes colors.
