Kintsugi is Japanese gold repair ("Kin" means "gold", "tsugi" means "to join"). Broken items (usually ceramics) are joined together with urushi lacquer (traditionally, now glue is more likely to be used) then the repaired cracks are sprinkled with gold dust. The result is what appears to be a gold filled crack, which draws attention to the damage and highlights the story of the object, https://en.wikipedia.org/wiki/Kintsugi
Gintsugi
Gintsugi is "silver repair", using the same process as Kintsugi but with silver power instead of gold ("Gin" means silver).
Other Lacquer Repairs
As Kintsugi and Gintsugi were gold and silver coated lacquer repaired cracks, sometimes these repairs were made using only colored lacquer.
Staple Repairs
Another old repair technique, in many ways the opposite of the decorative kintsugi repair, is the purely functional staple repair. In this technique, the object to be repaired is fitted together, then holes are drilled along the cracks and metal staples are used to hold the pieces together. This technique was common throughout the world in the 19th century and earlier, prior to the invention of strong adhesives.
Tinker Repairs
Similar to staple repairs, these are repairs to much-loved objects that are arguably more practical than visual. These are objects where broken pieces are replaced instead of glued. Examples include a broken teapot spout replaced with a metal tube, handles replaced with ivory, or replacement lids.
Boro & Saki-ori Fabrics
Boro fabrics are made from a patchwork of primarily indigo dyed fabrics. Often used as quilts, blankets, or clothing. Saki-ori fabrics are made from rolled strips of fabric. Often used as obi (kimono sashes). https://en.wikipedia.org/wiki/Boro_(textile)
