Repairing a broken photo frame with kintsugi.Clean the object before starting the repair.|In kintsugi, cracks are repaired by filling them with raw urushi.

First, carefully wipe away any dust or dirt from the surface of the vessel.（for reference：https://makie-kintsugi.com/en/17042026en/）
Then, slightly dilute the raw urushi and use a fine brush, holding it upright as you work.

Allow the raw urushi to fall naturally from the tip of the brush, placing it gently into the crack little by little.

After a while, the raw urushi will slowly seep through and appear on the opposite side of the crack.
This is a sign that the urushi has fully penetrated deep inside.
