You're the one going on about the quality of the engineering experience........ now you don't like it when other less inspiring examples involving granite claims are pointed out.

Wow..... so your chromium mirror is less flat than a just mirror-like polished granodiorite surface from ancient Egypt, which is not actually a mirror thus the repeated use of the term "mirror-like". So did you notice any internal reflection in your mirror because it's seemingly missing in the claimed measurements of the granodiorite even though it's made with medium to coarse-grained transparent quartz grains and medium to coarse-grained translucent feldspar grains that are polished to a mirror-like consistency allowing the light that does not reflect off to penetrate into the rocks surface and reflect around?
