This page is in need of a diagram. I think I know how it works, but not well enough to trust myself to draw such a diagram yet. Shinobu 02:48, 4 January 2007 (UTC)
68.188.203.251 ( talk) 20:34, 8 November 2012 (UTC) This may be an example of an early laser produced by coherent light. An example of early physics as are the standing water bowls. http://amasci.com/miscon/coherenc.html
See Herbert_Maryon#Later_years. I attended his lecture on 2 May 1962. At that time he offered a very plausible and satisfactory explanation of the secret. He said that on close examination of the back, he could see that the pattern to be projected had been deeply scored into the back with a very thin chisel. He speculated that this was done on the as-cast metal. When the mirror face was subsequently polished, the strain built into the metal by the chiseling produced the minute distortions of the surface that are needed to create the projection effect. His explanation appeared to satisfy the metalurgists present. However, I do not know of a written record to cite. AJim ( talk) 06:49, 20 June 2019 (UTC)
The article mentions an ancient Chinese book about these mirrors. Soon after, there is a phrase with an unclear antecedent to it : "Although it eventually got lost.." Does "it" refer to the book, the knowledge of the process, or what? Pete unseth ( talk) 20:36, 13 July 2022 (UTC)
Sorry for my lack of understanding as English is not my native language
in the introduction the sentence: "[...] appears to become transparent" is being used.
It seems like transparent is the wrong choice of word and should be replaced by "reflective" or "genuinely reflective". Also meaning is unclear, but transparent seems clearly wrong.
Did they perhaps mean "the mirror appears as a flat mirror when looked upon from the front side" ?
I'm hestitant to make an edit though, as this may be a lack of understanding on my side. Oliver Grüne ( talk) 20:59, 3 November 2023 (UTC)
