Cinnabar has a slight lead over quartz and I'm not happy about that! This is the start of a *long* thread for #TeamQuartz which I'll be updating throughout the day.

Quartz is my all time favourite mineral. Despite its simple formula (SiO2), it can be found in a variety of colours and morphologies 1/?

A big, round hollow rock (geode). The vanity is filled with white quartz crystals, and around the outer rims are grey coloured bands of agate.
Several crystals of pale purple amethyst rising out of a groundmass. The crystals are hexagonal prisms with pointed pyramidal tips.
A lump of colourless and transparent quartz filled with black needles of tourmaline. Label text: Quartz enclosing long needle-like tourmaline crystals. Locality unknown.
A brown polished slab of tiger's eye showing an optical effect called chatoyancy, where there are bands of gold which appear to glow.

It’s time for familiar favourites! Do you prefer the ominous scarlet of Cinnabar, or the familiar charm of Quartz? One needs to be handled with care, while the other is the cornerstone of every childhood rock collection. Which will it be?

A fact for the #etymology nerds! The word quartz describes one of its physical properties. It comes from the German word "Quarz" which has origins in various Slavic words for "hard" (e.g., Czech "tvrdý", Polish "twardy", Serbian/Croatian "tvrd"). Quartz is a pretty hard mineral as it's 7 on the Mohs hardness scale

The Mohs hardness scale. The left column shows the hardness of minerals: Talc is 1, gypsum is 2, calcite is 3, fluorite is 4, apatite is 5, orthoclase is 6, quartz is 7, topaz is 8, corundum is 9, diamond is 10. The right hand column shows the hardness of various everyday objects: A fingernail is 2.5, a copper penny is 3.5, a knife/glass plate is 5.5, a steel nail is 6.5, a masonry drill bit is 8.5.

I know many people are upset ice didn't make it into #MinCup23. Well, why not vote #TeamQuartz? The oldest name for quartz is the Greek word κρύσταλλος (kristallos) which was first used 300-325 BCE. Kristallos means cold - it was believed that crystals were a type of ice that couldn't melt because it was made by the gods ❄❄❄

Art lovers! Vote quartz! There's a long history of quartz being carved into beautiful pieces.

Have you ever visited a museum or gallery and seen something carved out of rock crystal? Well that's just a colourless variety of quartz. This is a Fatimid (#Egyptian) jug carved from quartz, late 10th to early 11th century

Just look at all the detail you can carve into quartz! This is the Lothair Crystal, a 11.5cm wide piece of rock crystal engraved with scenes from a biblical story

A quartz oscillator is used to regulate time inside most watches and clocks. This is because quartz is piezoelectric, which means that when it’s squeezed, it generates an electric current. This also works the other way round too: when an electric current passes through it, it vibrates at a certain frequency. The quartz oscillator is circled in the picture below

The quartz inside the oscillator is shaped like a tuning fork and when a current passes through it, it vibrates at a frequency of 32,768 Hz (32,768 times a second). The circuit in a watch/clock counts the number of quartz vibrations and uses it to generate a regular electrical pulse at a rate of one per second. This then powers the gears or the LCD display in the watch/clock

This website provides a great summary of how quartz clocks work: http://explainthatstuff.com/quartzclockwatch.html

So remember, whenever you check the time, you should thank the tiny little quartz crystal vibrating thousands of times a second!

There is a lovely Hungarian poem about a family of clocks. The great-granddad was an hourglass, then there are clock towers, and alarm clocks, and finally the great-granddaughter is a quartz clock, and the line is "she has a grain of old sand in her heart." 🥰

You can read the poem here (with Google Translate, probably...). I had a translation somewhere but I can't find it now...

Amethyst is a purple variety of quartz whose colour is caused by iron replacing silicon and then exposure to gamma radiation. Its name comes from the Greek amethystos (not drunk) - it was thought that amethyst could cure drunkenness 🥴 #TeamQuartz #MinCup23 #minerals #mineral @MineralCup 10/?

There is a "Greek myth" going around in esoteric circles about Dionysus and Amethyst, but it's actually a 17th century fakelore invention. Probably based on this belief.

Fun fact, the Hungarian version of D&D had gemstone-based magic, and lucky characters got to use amethyst to purify alcoholic drinks 😄
