I promised I’d be nice to #Quartz this #MinCup, although SOME people think it’s mean to point out you can access quartz’s electrical properties by hitting, squishing, or sawing it.

So, fine. Strategy tip. Why not tap existing Steven Universe fans to recruit voters?
The .gif opportunities are amazing considering Amethyst (the purple gem of #Quartz) is a major character.

Here she is getting a helping hand from #MinCup2018’s champion #Garnet:
One of the reoccurring #MinCup2019 arguments is that #Quartz is more stable than #IceMin at surface temperatures.

You’ve got a .gif for that. NO ONE USED IT THE ENTIRE CUP. Come on, it’s in the first handful of “Amethyst Steven Universe” .gifs pre-loaded into the Twitter app!

I’m totally amused how #quartz is catering the pity vote. All of #MinCup was created to make it feel special, yet every year other minerals win. Poor quartz.

Meanwhile #calcite is both fun & a climate indicator.
#Calcite is a mineral with neat optical properties, fizzes with acid, flags your attention when you stumble on to an ancient sea floor in the mountains, was a critical plot point for the premiere of #Stargate #SGU, and tracks climate.

But I lost a bet.

So. #Quartz.

It’s most of Earth’s crust. If you’re only learning one mineral, quartz is a good default guess.

I can’t help with ID more than”uh, it’s hard?” unless it happens to be a pointy crystal, but I’ve never found those in the wild. It’s the white bits of granite. Large quartz crystal with plastic dinosaur

We’re in the semi-finals of #MinCup2019 & I Have Opinions.

This is the year of #ClimateChange, the year we hit the tipping point of enough people caring to finally get to the large-scale hard work.

Our winner has to be ice or #calcite (tomorrow’s semi-finalist). #IceMin
#Olivine is a good mineral, a former 2017 #MinCup champion & one I campaigned for in past years.

It has so many cool quirks, including making green sand (!!). But it already won before.
Every year, people are startled to learn #IceMin is a mineral!

It’s naturally occurring, solid, has definite composition, & a repeating crystalline structure. As long as you find it in the wild, it checks every box.

Want it solid at room temperature? Ice VII trapped in diamond.

It’s the last match of Round 1.

#Halite is salt, the deliciously lickable mineral.

#Serpentine is an entire group (including asbestos) sneaking in to a single-mineral competition.

You know how to vote.
I went off about #halite recently. But surely Hot Tubs of Despair is enough by itself to earn your vote:
To be fair, I totally love #Serpentine. It’s a highly-pettable green snake of a rock that makes wine tasty.

Just don’t lick it.
Or breathe it.
And it’s still a cheater of being a whole group.

I had exactly 30min entry-to-exit to explore @hmns.

I’d heard they have a solid collection of trilobites & the massive cut blue sapphire Siren of Serendip is a special exhibit.

But with the clock ticking down, I raced up the stairs & tumbled into Cullen Hall of Gems & Minerals. Museum wall sign of icons indicating different types of exhibits
#Crocoite: Shiny red-orange spiketastic lead chromate.

Despite being named for colour-matching saffron, lead makes it firmly “Do Not Lick.”

This particular spikefren is from Adelaide Mine, Tasmania, sticking with “everything cute in Australia can secretly kill you” theme. Adamantine red-orange long prismatic crystalsAdamantine red-orange long prismatic crystalsAdamantine red-orange long prismatic crystals
#Fluorite: a honkin’ massive cube of calcium fluorite with that particular dull-waxy translucence I wanna pet so bad.

No UV light to see if it’d fluoresce pretty colours for me.

Oh no. It’s the most contentious time of the year for geo-folk. I usually stay out of it, but some of these minerals are going to make me stan hard.

Lineup below. Hashtag to Follow or Mute is #MinCup2018
Olivine is the defending champion. Here’s why it’s badass from my Ode to Olivibe last #MinCup:
