photo Marbleized clay


Marbleized clay (neriage) ceramics are made by layering or combining different colors of clay. A wide variety of patterns can be produced depending on how the clays are combined, with the cross-sections of the finished pattern appearing on the surface of the piece.

Different colors of clay contain different elements, and care must be taken to make sure that the pieces don’t crack or come apart. The finished piece shows the same pattern on its inner and outer faces.
