Found these two items last year and never thought much of them. I started looking at them and i thought i could post them on here and get some opinions. Thanks alot.

what was the context you found them in? the first one looks ceramic

 

[unclemac]

it looks a lot like a weathered kiln shelf support

They were both found is a lake that was drained. Wow thats exactly what it looks like! Thank you!

Now the last one looks to be what we find here in GA. If it is then its called a roller pestle. I haven't found a whole one yet just 2 pieces in 2 different fields so no match yet.
