Above are three pieces of fabric I rust dyed using an old coffee can lid in 2003, each piece of fabric has varying stages of rust on the surface depending on their position in the rust bundle layer. The piece of fabric to the far left was closest to the metal lid and therefore has acquired the greatest amount of rust on the surface. The iron oxide particles are so thick that they shimmer as just like metal.
