the accidental plater
Here is what goes on.... I bend a thin wall brass tube to shape then I have
to melt the bending medium out of the pipe with a torch. This causes a black scaling to show up on the outside of the pipe. To remove this I dip the pipe in a 50/50 mix of muratic acid and water. This in turn plates the pipe with very thin copper that I have to buff off. I know the acid is leaching copper and plating later pipes but what is the science behind this? Why does it plate?
