Making Kokuso / Urushi putty
Make Nori-Urushi by mixing Ki-Urushi and rice glue, about the same amount each.
Then mix sawdust into Nori-Urushi, this will become a hard urushi putty, called Kokuso. It’s consistency is like a soft clay. You can mix a little bit of Jino-ko (rougher powder than Tono-ko) to make harder putty.

Apply the Kokuso on to the chipped area using spatula or a stick. Apply pressure to the area using your fingers. You can later cover the area with clingfilm and let the clingfilm hold the putty in place till it half hardens.
Place in a box about a week to allow Kokuso to set.
Please remove the clingfilm with in 24 hours..
Try not to apply more than 2 mm thickness of Kokuso. Ideally application is 1mm at time. If it is more than 2mm thickness, you’ll need to make several applications a week apart.

When set, Kokuso’s surface will look rough.
Sand down Kokuso using sand paper with water till a smooth surface is achieved. Take care not to damage the surface of the item with sand paper.
