Calcium carbonate (Chalk)

Used as a DYE ASSIST or MODIFIER in natural dyeing. Chalk can help to boost the colour uptake on certain dyes, including Madder, Munjeet and Weld, enabling more pigment to bond with the fibres by creating less acidic conditions.

TO USE: calculate amount required for .5% WOF (weight of fibre), which means half a percent. Approximately 1 teaspoon per pound of fibre. Weigh and dissolve in hot water. Add to dyebath before entering fibre. For silk, stir into dyebath after dyeing is complete and taken off the heat, then soak fibre overnight.

Dye solutions containing chalk may be safely disposed of down the drain or just poured outside in the garden.

CAUTION: wear a mask when handling powders.
