Quartz: the Series

The α- Alpha  and the β- Beta

The Science & Art of Quartz.

SiO2

Our most beloved gemstone, in its myriad forms…Eleven crystalline and 2 non-crystalline minerals comprise silica (SiO2), though Quartz is the most common form. In our landscapes, in our lives…
Twelve percent of Earth’s surface is quartz, and a full 20% of the whole crust is Quartz.

Geologists have plotted the various forms of SiO2  over the years, culminating in the diagram to the left.

My SiOinterests these days, and most of my life actually, lie in the blue and pink  areas on the diagram:  α-quartz and β-quartz, respectively.

α-Alpha and β-beta quartz occur in all igneous, metamorphic and sedimentary rock types. Within the alpha and beta fields lie a seemingly vast array of different rock types, all of which comprise quartz.

Beautiful enough for gemstones. Revered since antiquity. The ancient Egyptians were gifted artisans whose use of blood-red Carnelian—one of the Quartz gemstones—is iconic and legendary.

It’s ALL Quartz…

Trace elements (e.g. iron) produce the colors we see in all forms of Quartz, though it is not color but size and  translucency that are the keys to the Classification of Quartz.

From Large to Small…Macro to Micro to Crypto. Size matters not only in how Quartz gemstones are classified, but how they come to display the endless and gorgeous variation in color and patterns of spheres,  bands and layers–whether smooth or crenulated. And why we love these humble stones more than diamonds.

Today, it’s all about Macro. Following are a few examples of the flavors of Quartz whose crystals are large enough to see without magnification. Tomorrow, the small stuff.

Macrocrystalline: Crystals are easily identified without magnification.

These Amethyst crystals are an example of Macrocrystalline Quartz.

The crystals do not have to be whole, perfect and complete like these. Some Quartz is quite coarsely crystalline yet doesn’t display the crystal habit of the mineral.

Rose Quartz is a type of Macrocrystalline Quartz that does not form crystal faces, but is composed of many intergrown crystal ‘sub-individuals’

Citrine

Second most popular Quartz gemstone…Amethyst is first.

Ametrine

A naturally occurring variety of Macrocrystalline Quartz comprising zones of Amethyst intergrown with zones of Citrine.

Ametrine cut perpendicular to the c-axis of the crystal. Is that freaking cool or what???

The Temple of My Imperfection – 2019

Here we go again…—that moment when you finally realize that all your efforts toward achieving perfection will never be enough.

Seizing the Wabi-sabi

 Wabisabi (侘寂) represents a comprehensive Japanese world view or aesthetic centered on the acceptance of transience and imperfection. -Wikipedia

crProbably wabi-sabi was first named for what happens to pottery subjected to the hellish temperatures in kilns, around 2,000ºF (~1100ºC). During the firing, the intense heat vibrates all the bonds that hold the minerals together until they come apart, and their constituent ions and molecules cruise around in a melted bubbly mixture that resembles lava, an igneous rock.

The kiln cools, and the pottery solidifies. Sometimes a gas bubble in the glaze pops at that moment and a little crater forms. Or maybe the glaze didn’t come out with a uniform color, or part of it dis-adhered from the pot and crawled away. Or the tea bowl sagged into another pot.

Classic wabi sabi, telling the story of a unique and unrepeatable moment of creation, fired and frozen in time.

Such wabi-sabi moments manifest keshiki–the landscape of the clay; these imperfections do not in any way interfere with the functionality of the piece, and it would be enormously wasteful to throw something useful away because of a surface imperfection.

One over Infinity

SphericalCow2I like to think of firing pottery as a sort of ‘backyard metamorphism’ that changes the pottery, essentially a sedimentary rock, into a metamorphic rock.

I have even made the statement publicly, that kilns are science laboratories in which ceramic artists perform experiments in geology and thermodynamics, which is a branch of science that deals with the advanced secrets of the Universe.

We have learned a great deal about the behavior of matter through experiments that rudely resemble the actual physical universe, tweaked by precise mathematical equations that ignore much of the almost infinite variation therein. Somehow we get close enough that the pieces fit together in rude sorts of ways.

Potter’s kilns on the other hand, much more closely approach the actual imperfection that brought us all the rocks on Earth. And the universe. With a great deal of faith, you consign your piece to the kiln. The wabi-sabi is impossible to know or quantify. There are no round frictionless cows.

Pray to the gods of fire, electricity, gravity and magnetism, that what comes out resembles the vision in your mind. Let me take a moment to calculate the likelihood of that.

One over infinity.

There’s always some wabi-sabi.

A Wabi Sabi Moment with Georgia O’Keeffe

O'Keeffe-(hands)I grew up looking at O’Keeffe art—being that she lived in New Mexico, where I was born and spent most of my life. I’d seen her paintings in books and posters for years. Standing in front of famous paintings in real life—no photograph holds a candle to that experience. It’s not just the colors being more alive, or that you get the true idea of the size of the painting. You are close, very close to the act of creation.
And once, I stood mesmerized in that very moment, as close to a painting as the cops at the Georgia O’Keeffe Museum in Santa Fe would allow. I could not take my eyes off it: a single paintbrush hair embedded in a stroke of color. I felt as if I was there in that one moment when Georgia O’Keeffe stood before this very canvass. A million brush strokes in her long life of painting…and there’s this one that put in that single, unique moment of exquisite wabi-sabi.

It was breathtaking.

I’m glad she didn’t see the hair; surely she would have plucked it out. I would have, in the name of flawless perfection that is found only as a concept within the part of the human brain that dreams of round frictionless cows.

Imperfection: it’s what makes the world

The Hope Diamond
The Hope Diamond

Not even crystals are perfect; they all have wabi-sabi.

They found this one really big chunk of blue diamond, cut all the wabi-sabi away, until it was perfectly huge. Hugely perfect. They called it the Hope Diamond—hoping for another humongous one like it.

One over infinity. It happens. But it’s all the other instances of imperfection that comprise the whole dang universe. The perfect parts are so few as to barely exist at all.

I’ve never made a perfect pot, never wrote a perfect book, never been a perfect anything. I’ll continue to put it out there, though, as long as I have a heartbeat. I am but a fragment of the whole wabi-sabi universe unfolding.

I just don’t know what else to do with myself.

The Ants Go Marching…and marching…and marching

…until death do they part.
………………………………………………………………………………………………………………………………………………………….

Ants-300x240Us and Them

Ever since I wrote Corvus Rising, I’ve considered in great depth and detail how the other living beings on Earth are more like us than not. We humans are fond of viewing our species at the top of the evolutionary ladder that we invented to explain the differences in anatomy and intelligence between Us and Them.

Our species is evidently highly favored: the very Deity we invented created Us to have dominion over Them.

More and more, however, it is apparent that our world view of creation is all wrong.

In the case of the corvidae (crows, ravens, magpies, jays…) we now know that their brains are very nearly the same size as ours (proportional to their bodies) and that they are not only intelligent, but sentient as well. (The Gifts of the Crow, Mazluff, 2012)

And we know that they talk to each other, as shown by Michael Westerfield’s marvelous book, The Language of Crows, whose recordings of crows and ravens dialogs in a variety of situations tells us their speech is not just about looking for a mate to make little corvids with.

Then there’s that little pufferfish, whose connection to the Universe I share. Blows me away. We are all hooked into the same life-giving forces, by whatever deity you or I wish to call it. I like to call it Art.

Them Ants…

Ants are pretty cool; among my favorite books as a child was The City Under the Back Steps—a marvelous story of a couple of kids who magically get shrunk down to ant size.

Ant_Receives_Honeydew_from_AphidThe children are shown all around the colony by the ants, and were instructed (as I was) in many of the ways of all ants. For instance: the ants kept herds of aphids and milked them for the sugars the little buggers sucked out of the rosebush. They really do that.  (Read more about how ants milk aphids here…)

Natural science from a fictional children’s book: a marvelous way to learn.

I am a fan of ants, more or less. As long as they don’t invade my house or sting me.

I watched nervously one summer as a gigantic ant colony constructed a subterranean civilization around the size of Denver in my backyard.

Ant-Farm

The problem with a humongous ant colony in my back yard: their sheer numbers so close to where I live.  They kept opening up exits and entrances all over the place, including right next to the porch and back steps. Made me nervous.

These are the kind of ants with the big jaws on their heads connected a sack of poison on the other end that is at least a third the size of their whole bodies.

Black Garden Ant.

Ant bites are bad news. Painful bad news. Every time one injects me with its personal stash of formic acid, it’s worse than the time before. So I am looking a little askance at the city under my back steps. I don’t want them there, but there they are.

And I am outnumbered. Pathetically outnumbered.

My father used to pour gasoline down ant holes and light it. Horrifying. So are pesticides. I do believe the ants have a right to be alive and pursue their ant-like goals. Just not so close to my soft, living flesh.

I didn’t want to kill them. I just wanted them to move. So I flooded them out with the garden hose, a slow trickle of water that filled up the vast network of caverns and passageways. Ants do not have lungs, I reasoned, therefore cannot drown.
But they do float well.
Jillions of ants floated up and out; most found things to cling to and rode the current to edge of dry land where they disembarked.

As soon as I turned off the water, the ants went to work re-building what I had ruined. The next day, I filled the ant hole up again, and ants bubbled up again. When the flood stopped, the ants started building again. I marveled that none of them went belly up on the sidelines, waving their six little legs in the air, otherwise whining and bellyaching about unfair the universe is, or how hard their lives are.

We do that. The animals don’t. They get over it and get on with living.sad-bug-with-napsack-smaller

Why can’t we?

The end of the ant story: I kept watering the ant hole and they kept rebuilding. I admired the hell of them. No complaining, no retaliation. Just one foot in front of the other five, and with a pebble in each jaw, they rebuilt.

And I kept destroying. We went on like this for days, me alternately admiring them and destroying them; the ants just kept rebuilding.

Persistence is Everything

They finally moved. They got sick of it, evidently, of spending all their time rebuilding their colony after the continued disaster I brought them. So they moved, lock stock and nursery to the alley behind the house.

Beyond the reach of my hose…
