Nice. The gilt would evaporate rapidly with the dishwasher, and you would end up with plain white china.
I have found for one person, that it takes less time to handwash as it does to prep for the dishwasher, and I get a bit queesy thinking of the length of time the dishes sit fermenting while I accumulate a full load.
Having a tiny kitchen I tend to use the dishwasher as a drying rack!
