Initially, I was very pleased with my Mikasa Delray Bone China set.  I purchased it in April 2023.  I am now concerned about some of the dishes (plates and large bowls) showing brown areas after they come out of the dishwasher.  They have to be scrubbed with a light abrasive to get the brown colour out.  Each time they’re washed, this happens.  It’s not every dish, just a few.
