Carol responds:
I agree with your logic here, but surely it's neither a bucket nor a
birdbath. It's what we all thought it was when we first saw the
American cover of HBP, a cracked and ancient Pensieve. And the evil
Legilimens Voldemort has filled it with poisoned thoughts or memories
that create both physical agony and mental anguish. I don't have time
to check, but isn't the consistency of the potion neither gas nor
liquid but somewhere in between, much like the silvery thoughts in
Dumbledore's Pensieve but tinged with green like the light from an AK?

Whoever R.A.B. is, and especially if he's the young Death Eater
Regulus Black, he would not have been able to recreate such a Dark and
complicated potion. I'm quite sure that it magically refills itself
for much the same reasons that you've given. I do commend R.A.B. on
his foresight, though. I'm betting that he wrote the note and put it
in the fake Horcrux before he even entered the cave. My question is,
how did he know where--or what--the Horcrux was?
