The pizza plate of Masterclass is made significantly more stable sheet and also heavy. A bending of the sheet is possible by hand not readily. In addition, the holes were punched before the coating process. Rusting at the interfaces is thus with an undamaged coating ruled out first. The packaging is also noted that it has a double coating and is officially released for cleaning by dishwasher. This gives hope for a long life.
My expectations fully met the pizza plate.
