Electrolysis of metal detecting finds:
Material: AC to DC power supply (radio AC adapter) my choice is a 1.5-12Volt, 1Amp converter Stainless steel alligator clips (2) with a red and a black boot Stainless steel spoon (MUST be stainless steel) Pyrex glass custard cup Baking soda
Optional: Variable AC controller for input to AC adapter Timer adjustable in seconds Alligator “extra hands” Insulation mat
Operation: Mix approx ½ cup of water and 1 tablespoon of baking soda Connect NEGATIVE lead of AC adapter to the OBJECT to be cleaned Connect POSITIVE lead of AC adapter to the stainless steel SPOON Place the spoon in one side of the cup Place the object in the opposite side of the cup Place insulation mat between spoon and object
DO NOT LET THE OBJECT AND SPOON TOUCH
Adjust the adapter’s output until bubbles appear on the object and spoon This should yield approximately 5ma on a dime, 10ma on a quarter and 15ma on a large class ring. Amperage is calculated for surface area NOT diameter Check progress at 30-second intervals for the first 2 minutes If more than 2 minutes is required, check at 1 to 5 minute intervals depending on progress
Hints: Use lower voltage / amperage (less bubbles) on more delicate items Disconnect object and clean with water and baking soda periodically Do not splatter solution on counter or clothing Use a fan to remove sulfur odor from working area
REMEMBER: You can always resume electrolysis after checking its progress, but you can NEVER undo the destruction it may cause if left too long or done at too high amperage.
