This is a Bizen fired vase from about the year 1600.  It has a crack which doesn’t go all the way through, the vase doesn’t leak.  Instead of completing the break which is usually my first choice I am going to fill it in with sabi. First I have slightly widened the crack with a diamond file and then masked the crack with tape.  Next I will apply lacquer that has been thinned with oil of turpentine so the lacquer will flow into the deepest parts of the crack.
