#165100 - 17cm Floor Board - Kaya - Paulownia Lid - Kiura

This amazing goban came to Baduk Club from an antique dealer in Hyogo, Japan.

The board is 17cm thick, and has the usual candy color that Kaya wood takes on with age, highlighting the dark resin in the grain. It comes with a protective paulownia lid. It stands 28cm tall with legs on. It weighs just over 18kg. 

It looks like a textbook species of Kaya, with these indicators:

• The  Cut : it is Center Cut (kiura style) to show off the heart of the tree. 
• The  Grain : the lines are wavy, unlike shin-kaya and matsu. They are also quite thin because Kaya is a slow-growing tree so there are hundreds of rings.
• The  Weight : Kaya is dense because it retains its resin as it cures for 10 years.
• The  Size (of the trunk): You can see that the rings radiate outward instead of forming neat semi-circles. While kaya isn't rare, it does take 500-1000 years to grow large enough to be used for a go board.
• The Color : a warm candy color, the heartwood is a uniform tone. 
• The Scent : It has a subtle sweet smell like vanilla and cloves.

A plain-sawn board like this produces beautiful end-grain where both players will sit, and straight lines along each side. The top and bottom have cross-grains in unique patterns like a fingerprint. based on the heartwood of the tree. 

The legs are close to the same color as the board, so they may be Kaya but could also be Katsura. They are a bit dusty. Visit my  Care Instructions   to learn more about cleaning and caring for floor boards.

Kaya boards are cured for 10 years before they are made, which ensures that the wood has finished changing shape. One of the big benefits of a vintage board like this is that it has had additional time to continue aging, this means the wood is more stable than ever. And even still, the wood is soft so it provides a nice resonance when playing slate and shell stones (in contrast to the sharp sound that comes from hard materials like glass and bamboo).

The corners and edges are all quite good. The protective lid has done its job. There is very little pitting on the surface, common with soft wood over time, so the board was rarely used or was professionally resurfaced. There are a couple imperfections that can't be helped with a used board, please see the photos for details. Most notably, the underside has oil marks from being picked up repeatedly over time. White wax residue on the endgrain should clean up with a cotton cloth and a fresh treatment of paste wax.

Boxed up with the legs and the lid, this set weighs 21.75kg.
