I have a set of different sized baking tins all fitting into the largest one when stacked, but they’re coated, heavily used and now rusty so I need something more durable and non-coated (as my pans). I need three different sizes: a big rectangular one for lasagna, etc. and two smaller ones preferably fitting into the larger one for storage: one square and one rectangular. Anyone got good recommendations? Preferably made of glass but I’m open for other recommendations
