Cream of tartar is a popular natural dyeing assistant, commonly used alongside mordants like alum to enhance colour results and improve dye uptake. This gentle additive helps produce softer, brighter tones while preventing fibre damage during the mordanting process. It is especially valued in natural dyeing for wool and silk, where it helps create even shades with a smooth finish.

In natural dyeing, cream of tartar is not typically used alone as a mordant but works in combination with mordants to modify how dyes interact with fibres.

Cream of Tartar

What does cream of tartar do in natural dyeing?

Cream of tartar acts as a dye assistant, helping fibres absorb colour more evenly. It can also brighten shades and improve the softness of the finished textile.

Is cream of tartar necessary for mordanting?

It’s not always required, but it is recommended when using alum on protein fibres, as it enhances results and helps prevent fibre brittleness.

Which fibres benefit most from cream of tartar?

Wool and silk benefit the most, as cream of tartar helps maintain their softness while improving dye consistency.

How do you use cream of tartar in dyeing?

It is usually added to the mordant bath along with alum, dissolved in warm water, and applied before the dyeing process begins.

Safety guidelines

  • Wear protective gear - gloves, an apron or old clothing, a dusk mask when handling powders. 
  • Dedicated equipment - keep tools separate from your kitchen items. Use stainless steel or enamel to prevent reactions or colour modification.
  • Ensure the space you’re working is well ventilated.
  • Handle mordants and plant dyes with care.
  • Dye baths involve hot water, be mindful of burns or spills.
  • Dispose of materials responsibly.

We cannot guarantee exact colour results with our natural dye products. Each batch is naturally unique, contributing to the distinctive, handcrafted character of your finished pieces. For best results, we encourage experimentation, as colour outcomes can vary depending on fibre type, mordant used, and water quality.
