no there made of plastic those are the airpots i use and if you remove the blue screws the pot will unravel. IMO you dont want to put the air pot into a bucket the whole point of the air pot is to let air into the root system though the little holes in the side if you put the pot into a bucket you would restrict the airflow to the holes in the side. why do want to put them into a bucket? the pots are durable enough to handle already its pointless to put them in a bucket, you might aswell just use a bucket if you are going to that
