This set comes with Japanese clamshell and bowls that have turned brown with age.
The bowls have an opaque tone that takes decades to form. The patina of the bowls almost hides the density of the wood grain, which is very straight and even indicating it is probably Ash or Mulberry. Hairline cracks were sealed with wood glue to keep them from spreading. The bowls were then cleaned with turpentine, treated with a Monkey Wax polish, and given 3 weeks to cure. The bowls fit the stones snugly, so they are the small end of Size L.
The white stones are Japanese clams, which are slow-growing and therefore have incredibly dense lines. I would guess call them Snow-grade for these dense lines, but Japanese stones are not graded the same as Mexican clams. There are 180 pieces, and they measure 6.3-6.9mm thick. The undersides have some orange speckling, indicative of Hyuga Suwabute stones. Learn more about vintage stones on our Vintage page.
There are 181 black pieces, which measure 6.6-7mm thick. It is normal for the black pieces to be slightly larger than the white, so that they appear the same size when side-by-side on the board.
