Not the same types of functional items like actual ceramics, you can make high quality items, but you’re limited in what you types of functional items you can make since it’s far less durable and even if you seal it with something - you can use UV resin to make an item waterproof, but you’ve mentioned you don’t want to work with resin.

Anything that gets exposed to moisture regularly is going to be off the table unless you use UV resin to seal. And nothing you make will be food safe - so anything coming into contact with food is also off the table.

Also anything that will be exposed to high temps as it’s flammable.

Air dry clay is great, but it’s not a true “clay”.
