The 3/4 inch pipe was annealed and the coloration comes from that process.
Random lengths were cut from each, and without regard to cutting exactly straight.
Then the cutoffs were placed in a dapping block, again without regard as to even dapping.
Next, the cutoffs were flattened with a small brass mallet, resulting in the odd shapes. Which was what I wanted. Perfectly round ones would be boring!
The bottom row washers are partially textured.
The smaller washers at the top and right came from cutting a longer piece off the 3/8 inch pipe. They have considerable, but interesting distortion.
An interesting experiment which, I think, hold some promise.
