Copper | Copper Sulphate

Copper Sulphate is a specialist mordant and colour modifier used in natural dyeing to alter tone and improve colourfastness. A small amount added to the dye bath can shift hues toward deeper, richer greens, teals, and browns while increasing washfast performance.

Kraftkolour’s Copper Sulphate is laboratory-refined and suitable for professional textile applications where controlled results are important. It’s often used as an after-bath or modifier rather than a primary mordant, allowing artists to achieve subtle tonal variations.

Benefits

Copper Sulphate adds versatility and depth to your dye palette, making it ideal for experienced dyers who want to fine-tune colour outcomes.

Ideal Applications:

  • Colour modification in natural dye projects
  • Botanical dyeing on cotton, silk, or wool
  • Advanced studio and professional workshops

  • High-purity copper sulphate powder for controlled colour modification
  • Alters hues and enhances fastness in natural dye work
  • Use sparingly (typically 1–2% of fabric weight)
  • Can be applied in separate bath or as a post-dye treatment
  • Always wear gloves and avoid prolonged skin contact

Test on a small swatch first — copper can dramatically shift tone. Dispose of waste responsibly and never pour directly into soil or waterways.
