Etcher's Polished Copper Plate, 18 Gauge (.050), 4in x 6in
Polished Copper Plates, 18 Gauge - This is the same product as our Industrial Copper Plate, but it has been commercially polished on one side for those who prefer a mirror finish. The polished side has been covered with a plastic sheet to protect it during transport. For etching processes, it is necessary to stop-out the back. Plates are sold individually.
