old islamic turkish coffepot

I believe this is an old coffee or water pitcher.  Has a symbol that looks like it would be arabic?  looks like upside heart with something in it?? The screwa are riveted  and is made of either copper or brass.  the arabic symbol is the only identity mark I can find, however there is alot of balck stuff that could be clened off and possibly a marking under it, although I think its better to not clean until find out exactly what it is worth.
