Need help identifying bowls

[SaintSea]

My treasure hunting buddy and I were searching an area of Central Florida today and came up with 3 very interesting bowls. No, they weren't metal - but a molded clay. She found 1 and I found the other two. They were discovered in soft sand, 3 to 6 inches deep - below an ancient oak; in an area that may have once been the shoreline for a large lake.
Are they Native American in origin?
The 3 are virtually the same; each has a small lip from which a substance was clearly poured: the lip area shows signs of darkening.
There are no discernable markings/etchings.
The bowls are small: about 2.5" at the widest part and only 1.5" tall.
Any ideas?

Looks like a pottery crucible for melting and pouring lead. Did you find any musket balls in the area?

The natives could have used something like that, but in historic times. They could have also been used by the Spanish, traders, Americans, etc.

No musket balls in the area... as of this writing, my hunting buddies and I have uncovered 10 of them; all in the same vicinity. They are all in the same excellent condition, too.
