There are 27-steps to process raw clamshells into Go stones.
1.Collect raw clamshells. (Sand pump boat suctions clamshells from the sea bottom. Shells are mined in very deep sedimentation, which is several hundred years old. Today, we no longer collect them because Hyuga clamshells are no more available.)
2.Select and sort raw shells. (Discard bad shells)
3.Measure the thickness of raw shell.
4.Mark the cutting-out position on the shell.
5.Cut out.
6.After cutting out, separate shells based on the color.
7.Measure the thickness. Select and sort cut-out shells.
8.Surface polishing. (First, roughly)
9.Select and sort polished shells.
10.Surface polishing (Secondly)
11.Select and sort polished shells.
12.Finish one side of the shell. (Surface polishing)
13.Selection and resorting.
14.Finish the other side of the shell. (Surface polishing)
15.Selection and resorting.
16.Polish by hand (We spend long hours for this process. We can polish only 20 stones per 1 hour)
17.Smooth the edge of stones.
18.Dry under sunshine.
19.Breaching.
20.Dry under sunshine
21.Polish in barrel-shaped machine (Every stone polishes with each other.)
22.Drying.
23.Sort by thickness.
24.Selecting and resorting to find out damaged, bad-shape, defective stones.
25.Selecting and resorting (Grading) One stone is checked 2 to 3 times in this process.
26.Final selection and resorting. 27.Complete as one product.

*All these process require high level of skill and long experience.

Kuroki Goishiten can ship a wide variety of Go equipments all over the world. However, each country has different regulations or limitations for postal and boat service.

The shipping cost will be determined based on the size of package, weight, and destination.

Our shop is open Saturdays and Sundays, and you are always welcomed to visit us and see the manufacturing process of our Go equipment. However, sorry, we have no English-speaking staff now. Therefore, it will be impossible to give you guidance in English.

Answer

Sorry, we do not sell a wax for Go board. But we recommend that you will use beeswax (soft wax), because only craftsman can use very special wax, which is very difficult to handle by the customers.

Answer

When the leg is wobbling, you can adjust the height by shaving off the bottom of leg or attach a paper, or pulling out a leg with a rubber hammer slightly. The legs are hammered into the wood, not stuck in the table.

Answer

Here is an instruction on how to fix the crack on the board.
1. Apply strong adhesive or glue (for wood craft) between the cracks.
2. Both sides of the board should be pressed using a jack strongly after placing wood protection on both sides.
3.Leave it for about 10 hours.
4.After 10 hours, release the jack gradually.
5.The cracks will be strongly bonded together.

Caution:
Please keep the Go board away from heat source or stove.
Sudden temperature change and too dry atmosphere is not good for Go board.
