The final dated example is a seated Vairocana Buddha dated by inscription to 858. This Buddha is representative of the images of the 9th century, a time of political turbulence and the weakened power of the Silla rulers in the capital. During this time powerful land owners far away from the central government began to commission their own Buddhist images, as the inscription on the Borimsa (McR. Porimsa) Buddha states. These regional images began to reflect individual styles that differ starkly from the Kumseong tradition in the capital. The Borimsa image, for example, has a thick nose ridge, brow, and robes that differ from the Seokguram prototype. Additionally, while images in the capital were still produced in prestigious bronze, regional Buddhas begin to be made with iron, a material that was considerably cheaper. The production of iron images differ greatly from their bronze counterparts because iron images were cast piece by piece and assembled into a single image. This technique results in visible joints were plates were connected together and then probably hidden with thick layers of lacquer and gilding.
