Salt formations in my quench pot

The water evaporated in my quench pot and left salts in the water to form amazing patters around few silver drops.

I put soldered pieces in the water before it goes in the pickle pot to quench them.  The water is also used after pickle cleaning to remove the acid from the pieces. 

Pickel is a water diluted acid solution to remove oxides on precious metals produced from heating and soldering as well as glassy flux residues. When I cast new jewelry they come out black since the silver is covered with oxidation. Putting them in the heated pickle for a couple minutes removed all the oxidation and leaves them white.
