The actual process for Chrome Plating was developed in 1924 at Columbia University by Fink and Eldridge. They based their experimental work on a paper published by a scientist called Sargent. It has been claimed that a form of ‘spray chroming’ can be traced back to 1759 but the truth of that is open to conjecture possible?
