Q. I have a bowl mold that is 6 cm deep and it has a groove in its bottom part. What is the best way to make sure hard chrome will be plated in the groove? I am having a hard time to hard chrome the grooved part.

Q. Hello , I would like to know if it is general knowledge to use steel as a conforming anode for hard chrome plating, and if so, is there a copyright on the process of using such a method.

A. It is general knowledge NOT to use steel as anode for chrome plating. It dissolves and contaminates the solution, also gives other problems. Better use lead and if not possible use Stainless Steel.

A. I think that it is general knowledge enough to not be patentable. Then, it is not practical as it puts iron ions into the chromic solution which causes problems. I have used steel wire for a very precision anode for spaces where lead that thin was absolutely too flimsy. Tiny amounts of steel anodes can be used if you are using a porous pot or similar technology to remove the contaminants formed. Cast lead mats like those Clarence Peger proposed in his book are very easy and very practical after you get the construction knack down.
