Two widely used and interesting minerals! 🤔 It’s a tough choice, but we’ll continue on #TeamQuartz — did you know the outer rings of Stonehenge are mostly made of this mineral? eos.org/articles/sta...

I am #TeamQuartz but my son’s argument for #Graphite is that it’s “layers of the strongest and thinnest material known to man “ (graphene) and I thought that was worth contributing. Also they’re both hexagonal and that’s the best shape!

@lesuper.bsky.uy Sep 30, 2026, 4:21 PM

Worst of all, #Graphite is rarely ordered and stacking faults make #PXRD much harder to interpret correctly.

Two faves for both my art or physics voting scheme, but I have always been #TeamQuartz #MinCup26!

Quartz has been carved, used in pigments & the preparation of canvases since antiquity.
20% of the crust & representative elastic moduli, piezoelectricity & its role in clocks, electronics, GPS!

My mini linocut with quartz crystals and word “Quartz” in script in slate grey. Some of the facets of the crystals are printed onto collaged iridescent translucent paper so they have a pink to pale blue sheen.

This small linocut represents the chemical element Silicon, with its diamond cubic crystal structure shown in silver. Its symbol, atomic number and a couple of its forms are shown in lilac. Silicon is common in the Earth's crust in, especially in silicate minerals like the quartz crystals shown in each corner. The seafloor is litered with microscopic radialarians, which build their amazing skeletons with biogenic silica. Four such creatures circle the symbol for Silicon on the periodic table. The print is one of an edition of 14, each 6" x 6" (15.2 cm x 15.2 cm) printed on Japanese kozo paper.

I’m #TeamQuartz in #MinCup26 but today’s
#sciArtSeptember prompt carbon lines up with graphite, so I am sharing my #linocut of Millie Dresselhaus (née Spiewak; 1930 – 2017). She was a professor of physics & electrical engineering at MIT, known as the Queen of Carbon Science.

In this linocut I’ve
