Your piece will sometimes come out of the bath looking pink/salmon colored, with a dull or matte texture. DON’T WORRY! Luckily, it will still shine up with a few simple tools such as steel wool, a brass brush, a dremel tool with a wire wheel attachment, or a rock/jewelry tumbler.Several variables can contribute to this outcome. If using brightener drops doesn't improve the finish, then most commonly it is the result of either the amperage setting being too low for the surface area(below the target of 0.1 amps per square inch), or from oversaturation of copper ions in the solution from too much surface area of anode in ratio the the size of your cathode/design, and low distilled water levels. Using a 2:1 anode to cathode ratio, along with replenishing evaporated distilled water will help to maintain the copper to acid levels in your solution.If your plate is brittle, textured or glittery in appearance, then you may need to perform bath maintenance, which can be found in the FAQs section of my online tutorial.
