This weekend, my buddy Jon came over, and we used my garage chem-lab to silver-plate some brass hinge leaves for some fancy jewelry boxes he’s making. I had never electroplated anything before, and have been curious about the process since my undergraduate days. My impression, based on my survey courses, was that electroplating is messy and dangerous—one of those jobs it’s usually best to contract out to a speciality shop. Jon came prepared with a bucketful of supplies. He had the parts themselves, a benchtop power supply, a strip of stainless steel to serve as an anode, cotton plating pen tips, a strip of 0.999 silver to wrap around the pen tip and connect it to the PSU probe, copper wire to support and ground the parts during the plating operations, and three bottles of MIDAS-brand electroplating chemicals. (MIDAS, for the record, is Rio Grande’s house electroplating products brand.)
