I just loaded every dish that ever existed into my dishwasher and ran it.
No, really. Every dish. Ever. We broke into the neighbors’ houses and used their dishes and piled them up in our sink. Big medieval stoneware jugs, Greek and Roman pottery, 8,000 year old Babylonian dishes… all of them were in our sink, and all of them are in the dishwasher. (Yes, it’s a big dishwasher.)
Do you think Minoan slipware is dishwasher safe?
