Quartz is a common mineral, with some very important and uncommon properties. One is piezoelectricity. When quartz is squeezed, it generates an electric charge. Together, quartz and earthquakes can promote the formation of gold nuggets, that can be quite large. #Quartz #MinCup26

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.

Cuprite is used as a red pigment in glass, artificial gems, enamels, & ceramics. Colour can range from blood red to purple/brown in a reducing atmosphere & change to green in an oxidizing kiln. Halite is part of us, used in art: carving, watercolour effects, installations & EM geophysics. #MinCup26

I voted for cuprite because it is colorful and has an interesting crystal structure that very few other minerals do, and halite is just salt …but halite forms giant salt domes, comes in many colors, is essential to life, also forms nice crystals, and even fossils - plus the Wieliczka salt mine 😮
