Principles of natural dyes

1. Most natural dyes need both a plants extract and mineral mordant’ to make a permanent colour

2. The stronger the dye extract the more plant used the deeper the colour.

3. Mordants are always used in the same proportions. One can use less for a pale colour, but never use more, as too much of it can harm the fibre.

4. Time, temperature and concentration are the variables involved in any chemical reaction. Higher temperature means less time needed for dyeing, as does higher concentration of dye stuff.

5. Fibre should be pre prepared for the dye both. Pre wash fabric or garments to reduce sizing.

6. No rush. Preparing the dye can take long time.

7. Use big pots and plenty of room for the material to move freely, otherwise the colour will dye very unevenly.
