Made from plants

Just like a wine maker of a good chateau Tinctoria guards the quality of her products.

There is a greater variety in organic dyes than in chemical colouring substances. This makes the control over them complicated.

The composition of the soil and the actual weather conditions whilst growing will influence the final colour content of the plants. Furthermore other matters can happen. For example : to protect itself against wasp eggs, the oak produces gall nuts, which are used in the dyeing process. Gall nuts form at the same time a good breeding ground for other insects, which is the reason why the final colour varies.
