One has to watch carefully, as the small screw heats quickly. It is easy to pass the point where the screw has reached the desired blue-black color. Here we see the lamp in the background and the blued screw still in the bluing pan. Success!
Sometimes there is a lot of satisfaction in the old ways of doing things. Not only is the screw's finish consistent with the rest of the screws in the clock, but it was fun to do. It required little in the way of supplies and only one old kitchen spatula was harmed in the process. I like to think that it has been given a new lease on life. I certainly wasn't using it much in the kitchen! As time goes on, I will drill more holes to accommodate different sizes of screws.
