I second the Pyrex jugs. I have a 2 cup and a 4 cup.

I found some borosilicate microwave pan thingies but they vary in price and the reasonably priced pans seem to have one style www.amazon.com.au/s?k=borosilicate+microwave+pan&…

There are also ceramic mini cocottes. I think Aldi had some months back but stock seems random
