Is this set really 12 pieces or 18?

The name says 12-piece while the listed piece count says 18. Ask the seller to confirm the exact contents before ordering, since a 12-piece set is usually service for four.

Is Corelle glass safe in the microwave and dishwasher?

Yes. Corelle's tempered glass is made for both microwave and dishwasher use. Avoid broilers, stovetops and open flame.

How does it compare with stoneware or porcelain?

It is much lighter and stacks in less space, and it resists chipping better in normal handling. Stoneware feels heavier and more substantial but takes more room and chips more easily.

Will the black pattern fade or scratch?

The pattern sits under the glass surface, so it holds up well, but dark rims can show fine scratches and wear with heavy use. Hand washing helps keep it looking new.

Can I add matching pieces later?

Corelle sells open-stock plates and bowls in many patterns, but matching the Arica black rim exactly depends on availability. Check that the pattern name matches before adding pieces.
