This is one of my CRENELATED COPPER SINKS integrally cast in a polished concrete counter top. By this I mean, I MAKE AND FORM THE SINK SEPARATELY FIRST,then it is cast in the counter top.For this I partner with Patrick Miller of bohemianstoneworks.com Those large pebbles on the left were collected by the client at the beach and incorporated into the piece. The THE WHOLE UNIT IS CAST UPSIDE DOWN in Pat's shop using high performance cement of his own proprietary mixture,on specially made VERY FLAT casting tables(which I built). There is an array of small pins welded to the side of the sink buried in the mix so that it cannot escape... I make this crenelated design in stainless steel and bronze as well,in both integrally cast versions(as you see here) and in the surface mount configuration as well.All my sinks are at least 1/8 inch thick. The process for shaping the sinks is done by PUSHING a round flat disk down into a female (hemispherical)form (or several)with an 85 ton arbor press. The edges of the sink deform as I push it down,and I've come to learn how to control those "CRENELATIONS" somewhat. So each sink is shaped slightly differently and remains one-of-a-kind even though I start with a similar round flat disk blank on all of them. I have been a student of organic design(shapes from Nature)all my life. This process of UNIQUE REPLICATION satisfies my appreciation for distinct hand made artifacts while at the same time qualifying as SERIAL MANUFACTURE.
This is stunningly beautiful! I love copper, and when it is highly polished like this, it is prettier than gold, in my opinion. Is there some kind of sealer on it to prevent tarnishing? How does one properly clean an item like this, to make sure it doesn't become discolored?
