Chlorophyllin is a beautiful green powder derived from the extraction of chlorphyll from the leaves of plants. It is a well known natural dye used in foods, cosmetics, & in fabric dyeing processes amongst many other applications. It is a very strong dye so you don’t need very much - 5g is sufficient to dye 200g hanks of wool to a dark to medium green colour. Obviously you should always experiment to get your desired shade before adding expensive wool yarn or fabrics. Shades obtained can vary from olive green through to dark to pale bluey/sea green green colours, & is very stable & colourfast. It provides a rich colour to all your dyeing projects. To use in fabric or wool dyeing, mix a paste with 5g & a small amount of water, & add the paste to your dye pot. Add the wetted, mordanted fibre & gently simmer for 45-60 minutes stirring occasionally. Leave to cool, & wash. Pack size supplied is 20g Chlorophyllin Extract Powder - 20G 200% Natural Plant Green
