Gallnuts (Cynips gallae tinctoria) Galnoten (NL)
Gallnuts can be used as a dye and a mordant.
When a gall wasp lays its eggs in an oak leaf, the leaf wraps itself around the eggs in response and starts to proliferate. The leaf serves as a shelter and food for the larva. The gall nut grows into a hard ‘marble’ and when the larva has hatched, it disappears through the small hole in the gall nut.
The gallnut contains a lot of tannin, which is a mordant. Therefore, there is no need to stain before painting.
By combining gallnuts with, for example, iron sulphate and bluewood, it is possible to achieve black.
Gallnuts have been used to make ink since the late Middle Ages. For this, you need a binding agent, such as guar gum and Arabic gum.

Oogst Natural Dye product philosophy
Tiring of quick-fix culture and instant gratification? Frustrated with the monotony of modern life? Are you yearning to make elegant and stylish products yourself?
Instead of falling victim to the ‘quick-fix’ mentality, take your time and create something relatively insignificant by today’s standards. Get back to nature with natural dyes.
The earth is our most precious resource. It provides everything we need, including the landscape in which we live, the food we eat, the air we breathe. It’s our foundation, grounding us in a steady rhythm of seasons. The fast pace of modern life has shifted what is considered valuable. What we need and even who we are has been redefined by a consumeristic society.
Let go of the impulsive convenience mindset. Break free from the urge to just consume. Create something new, make something on your own – using natural dyes – and reconnect yourself with nature. Discover the pleasure of Oogst natural dyes for yourself, getting back to basics with colours directly from nature.
There is something to be said about the process of creation. It is not only the final product that is important, but what led to its creation. We want you to experience how it feels to make something with your own two hands.
And why should that be complicated? The truth is that for hundreds of years before synthetic dyes came along, common folk were creating their own dyes.
We’re bringing back the lost art of natural dyeing. It’s easy to buy what you need at the stores just like everybody else, but when you dye your own projects you come away with something truly unique.
