Quartz: the Series

The α- Alpha and the β- Beta

The Science & Art of Quartz.

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 SiO₂interests 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

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

Probably 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

I 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

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

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.

Sentience and the Art of Everything

A Guineafowl Pufferfish, Hawaii — A Pufferfish

A recent blog post, And then it was Art, featured a delightful video of a pufferfish creating a work of art in the sand, as if he could somehow visualize what the final piece would look like. That’s what artists do—we create a physical manifestation from an internal vision. Who knew a little fish could do that too? Surely it is not a sign of high intelligence and sentience as in humans, but merely an instinctive mating ritual in the pufferfish.

Heretofore, I’ve been guilty of a quite bigoted attitude, you might even say species-ist, against pufferfish everywhere. I have in a most unaware manner, equated art with superior intelligence and sentience, and discounted the very idea that this tiny fish could be either. For most of my life I have bought into that dogma.

Until the pufferfish came into my life.

What if the pufferfish is actually highly intelligent as well as aware?—but how would we know? When the standard of intelligence is set by us, and has everything to do with our anatomy?

So what is sentience, exactly?

Well, the definition evolves over time, but has nothing to do with intelligence…

sentient: noun \ˈsen(t)-sh(ē-)ən(t)s, ˈsen-tē-ən(t)s

1: responsive to or conscious of sense impressions <sentient beings>

2: aware

3: finely sensitive in perception or feeling

And:

sentience (ˈsɛnʃəns) n.

1. the state or quality of being sentient; awareness

2. sense perception not involving intelligence or mental perception; feeling

Some say that the ability to plan, visualize, and construct is a sign of sentience. That sounds like architecture, actually. Art and engineering combined if we do it; instinct if another animal does.

Just because we can’t hear it scream…

Sense perception means the ability to feel pain and loneliness. And to suffer. I wonder if there is a living creature anywhere that does not feel pain? Or loneliness. Everything that lives probably feels pain. I’m thinking maybe microbes don’t, but how do I know? Just because they’re microscopic? Am I again being species-ist, also known as myopic?

EcoArt

Maybe art and sentience have nothing whatsoever to do with one another. Consider also the lush green moss gracing a quartz and pretty pink feldspar rock called Orthoclase. As if the moss was painting on the rock. Can we even consider sentience in a plant?

If you take a closer look, past or within the velvety green luscious amazing moss, there’s a few other creatures in the rocks. As it turns out….moss is an allotrope, meaning it’s a primary plant producer upon which the food supply of the entire animal world depends. Contrary to popular belief, moss does not eat rocks, it attaches to them in order to get water; it’s energy is derived from the sun, as is true of all plants.

So what’s the lighter green stuff? Not moss, not even plants. They’re the rock eaters, the lithotropes, aka lichen—microbes that feed off the chemical composition of rocks, or whatever they attach to. Lichen form a symbiotic relationship with the moss. Some are pale green, some are yellow, orange, they’re all amazing.

Are these creatures aware of their artful expression of living; their unique and endless variations of a verse in the great song of the Universe?

Am I?

Are you?
