Chrome dipping is also referred to as chrome plating and is used to add decorative luster to a hard or soft metal. The chrome dipping process requires a bucket full of premixed electrolyte, a cathode and an anode. The cathode is the piece of metal you wish to chrome. The anode is a flat piece of nickel. Both the cathode and anode are dipped into the electrolyte before a car battery is used to create a charge -- sending nickel particles from the anode onto the cathode to create a chrome finish.

1
Add the distilled water to the bucket. Carefully add the chromic acid crystals and sulfuric acid fluid. Always add ingredients in this order.
-
2
Lay a copper pipe across the top of the bucket.

3
Attach a copper wire to the positive battery connection. Tie the nickel plate -- the anode -- to this other end of the copper wire. Dip the anode into the bucket.
-
4
Attach a second copper wire to the copper bar. Tie the copper plate -- the cathode -- to the other end of the second copper wire. Dip the cathode into the bucket.

5
Allow the chroming process to commence for 75 minutes. The electrolyte mixture will begin to turn brown as the chroming commences -- an indication of microscopic pieces of nickel that are being removed from the anode and adhering to the copper plate -- the cathode.
