As long as the ceramics have been fully glazed with a food-safe glaze and do not have any metallic decorations, they are most likely microwave safe. Generally, brand name/corporate made stuff will be fine, but handmade can be iffy because a lot of really pretty glazes are not food safe.
Thoughts on microwaving ceramics? (Or even wood)
Hmmm no idea honestly?
