I explored the world of madder
Madder are the roots of the Rubia plant and gives a beautiful red colour. It was one of the colours the Dutch cultivated and trade the most, but it has almost disappear.
What can I do with this Dutch pround?
Can you make more colors with it?
How can I change the PH values of a dye bath and does it change the colour?
Can I reuse the madder of a second or even third dye bath?
Which mordant can I use?
