Sealing hairline crack

This antique plate has many chips and hairline cracks.
If the crack moves when you play around with the item, 
you better break the item along the crack before starting on its repair. 
Picture
File the crack with a diamond hand drill bit by hand
​to remove glaze around the crack.
Picture
Apply diluted Ki-Urushi (about 50/50 with turpentine).
If it's a narrow crack, 
​draw dots on top of the line where the pieces meet.​ 
After, place in a humid box for a few hours to a half day.
Picture
After a few hours, clean off the excess urushi.
Whilst cleaning, check if every big of the crack is stained by Urushi.
In some cases, dots might disappear
​when they go into the crack, if so, don't worry.
Picture
Clean excess urushi well, and keep in the humid box for a week.
If the line is fat,
you might need to repeat this process a few times
before you apply Sabi or putty.
Unfortunate cases
After the second attempt, some cracks will still leak.
If so, seal once more, and apply Sabi anyway.
​Then seal with Ki-Urushi again.
