Talk:2501: Average Familiarity

I've never even heard of olivine. I think most people have heard of quartz (it's the crystal in most electronic watches, and it's pretty), and I suspect feldspar is somewhere in between. Barmar (talk) 05:21, 12 August 2021 (UTC)

As a chemist, I heard of all of them but, fun fact, there is a mnemonic in the german language known by at least all of the elderly generation: "Feldspat, Quarz und Glimmer - die drei vergess´ ich nimmer!" thats "feldspar quartz and mica - i will never forget the three". These three are the main compunds of granite and obviously this was stuff the had to learn at school. If, in a group of silverheads, start the phrase "Feldspat Quarz und Glimmer ..." and there will always be someone to finish the sentence. --Pauliprinzip (talk) 05:45, 12 August 2021 (UTC)
