Does everyone else glasses dry completely? My thicker glasses do but thin glasses and the bottom of wine glasses don’t completely dry. Seems to me that the better comparison would be to ceramic and metal, where the silverware and plates are always completely dry by the end. People are talking about how glass has a higher thermal density and is more thermally conductive than plastic… maybe so but I think still a very low thermal density and conductivity, relative to the other things you put in your dishwasher. There has to be a reason that induction stove tops have glass surfaces. They are cool to the touch a few seconds after taking off the pan.
