Workflow

  1. Establish Baseline Dye

    1 day

    Dye control skein without modifier to record default color from species and mordant.

  2. Test Modifier Series

    2 days

    Apply ammonia (high pH), vinegar or citric (low pH), and iron after-bath shifts systematically.

  3. Record Color Shifts

    1 hour

    Photograph samples in daylight 5500K, note pH and modifier concentration for each result.

  4. Apply Winning Recipe

    1 day

    Scale successful modifier protocol to project batch with precise measurement and timing.

Reference Materials

pH and ColorStandard

Anthraquinone dyes in some mushrooms require alkaline pH (ammonia) to develop purples.

Modifier TimingFormula

Pre-mordant iron vs post-dye iron produce different shades — not interchangeable.

  • Ammonia Fumes

    Never mix ammonia with bleach — toxic chloramine gas.

  • Outdoor Only

    Ammonia modifiers outdoors or fume hood mandatory.

  • Iron Storage

    Iron liquor oxidizes — label date; avoid accidental ingestion.

Safety Notes

  • Use chemical splash goggles when adjusting hot dye pot pH.
  • Keep modifier bottles clearly labeled and separated.
