Madder Root used in dying, dates back to Prehistoric times. Our Madder is from Turkey and comes the Rubia Tinctorium. The coloring matter can be extracted by fermenting the root and then extracting with alcohol. This extract can be used to color spirit varnishes or be converted into an aluminum lake and used to color oil varnishes. It can also be used to stain wood various colors with the use of mordants. For those who do not wish to extract the coloring matter we sell synthetic Alizarin which is the active coloring matter in Madder Root. We stock both the whole and ground root.
