Gallnut is used as a tannin for pre-mordanting cellulose (plant) fibres such as cotton.  Made from tannin rich galls which form on trees as a natural defence mechanism against insects.  The galls resemble nuts, in that they are hard and generally round, but are not truly a nut.  

Used as a pre-mordant for cellulose fibres at 6-8% wof, the tannin step is very important for proper, colourfast dyeing.
