Woad is a member of the brassica family and happily grows throughout winter. Grows as a rosette, harvest the leaves as you would a cut-and-come-again lettuce, from the oldest leaves, discarding any that have browned.

Soda ash (sodium carbonate) is an essential alkaline agent in natural dyeing used primarily to scour (clean) cellulose fibers like cotton and linen, raise the pH of dye baths for brighter colours.

It is used at 1-2% of the fiber's dry weight (WOF) to remove oils and waxes before dyeing.

Soda Ash is considered non-toxic, but working in a ventilated area and wearing a mask and gloves is best practice whilst handling this powder. I recommend keeping any tools used for this process separate from kitchen tools. Alum acetate may be safely disposed of in a municipal water system by pouring down the drain.

This material comes in a natural biodegradable cellophane. We recommend transferring this to a glass or plastic jar for long-term storage.

Potassium Titanium Oxalate is used for the mordanting of protein and cellulose fibres. The Titanium aids in producing bright oranges with some tannins.

Use at 8-10% WOF. Dissolve in hot water. Add to the dye bath, add fibres and cook for 45-60 minutes at 75-90° C, stirring frequently.

Calcium carbonate, or ground white chalk. Used to neutralise any remaining aluminium acetate or iron mordant. Can also be used as an assist to 'harden' water, to aid in the deepening of shades in certain natural dyes.

Add 50g of chalk (calcium carbonate) to 5 litres of warm water. Fully wet the fibre in this solution and wring out, before rinsing thoroughly. This solution can be reused for up to 10kg of fibre.

Using fresh indigo leaves allows you to enjoy the offerings of this iconic dye plant, without the hassle of growing, extracting pigment and then preparing a vat. Fresh indigo leaves can be utilised in many ways using techniques such as the salt rub method and the ice blender method. These can yield incredible robin egg blue shades that are hard to obtain with other dye materials. The fresh leaf indigo process is best used with protein fibres - it has a particular affinity for silk.

*Pre-order, for despatch on Wednesday the 4th of February*

Each pack will be harvested on the morning of Wednesday the 4th of February, from our Tai Tapu farm plot and kept cool before being quickly vacuum-packed to retain freshness. It will then be sent overnight, and suggest using it within 24-48 hours of its arrival for best results. We recommend using 200-300% WOF (weight of fibre) to obtain the shades pictured. A higher WOF will obtain darker shades. Each order will come with instructions on how to process the indigo using the salt rub and ice blender method, and also carry fabric care instructions to ensure your colour is long-lasting.

Aluminium acetate is used for the mordanting of cellulose fibres such as cotton, linen and hemp. Use at 5-8% WOF.

Symplocos is a natural, plant based mordant. The leaves are a natural bioaccumulator of aluminium, and when harvested and groundintoo powder, these made an effective mordant. it can be used on both cellulose and protein fibres at 50% WOF.

Note that Symplocos does impart a yellowish shade onto your fabrics, and will therefore affect your final dye colour.

Aluminium Triformate is a room temperature mordant for both cellulose and protein fibres. part of the alum family, it is a more recent addition of mordanting options for the natural dyer, gaining popularity (particularly with wool dyers due to its temperature requirements) for its low-impact process (water & energy saving). It produces similar results to that of alum acetate, and can be used with a pre-tannin bath to help improve dye fastness. use at 5-10% WOF.
