Giving Thanks for Being Present

Those who know me know how excited I was to wake to snow. So excited in fact, that I awoke early, saw that certain glow in the sky through the window above our bed, and jumped up, not wanting to miss the day dawning. At just before 6am, I turned on an outside light for a minute and opened the door to receive the quiet that the flakes created. It snowed for a couple more hours before turning to…

So, I managed to find this little beauty!

It’s a really cool aquamarine specimen, with black tourmaline needles inside it, sitting on some muscovite mica and (I’m pretty sure) colorless fluorite.

It was in a display case with some other specimens with prices in the high hundreds to low thousands of dollars, so I was afraid to ask what this one cost. I couldn’t believe her when she said it was only $75.

Time to get my rocks off

The local mineral club is having their annual Rock, Mineral, and Gem show again! I can't wait to go see what I can find...

Please tell us more about characters assigned rocks 👀

Oh no my trap card! long post time!

Okay, the rocks that I assign to characters depend on a lot of different factors (mostly vibes), am I planning aesthetic matches? eg. rubies and garnets for technoblade? Narrative matches? eg. gypsum for dream? Character matches? vibe or function? eg. feldspar for techno, muscovite for phil? The result is a pile of different rocks assigned to each of my special little guys, some with more uhh tenuous connections than others.

Let's go over the rocks I assigned to the syndicate (+dream) and why:

First up, Technoblade and K-Feldspar:

This is one based mostly off of vibes. It's one of my favorite feldspars and Technoblade is my favorite guy. And orthoclase feldspar, or K-feldspar, is PINK.

But I am nothing if not able to make explanations for things that were initially just based on vibes. Let's look a little beyond, shall we? Feldspars are known for being very structured in the sense that they have two defined cleavage planes at 90 degrees to each other, making rectangular blocks with irregular ends. Techno, to me, is the pillar of support and structure to his friends, so a cleavage pattern that reflects that is fitting. (in contrast, I think Ranboo's character could be represented by obsidian, which is glass-like). Beyond that, feldspar is the most common mineral in the earth's crust, making up about 60% of the crust. In terms of Technoblade, this could represent his impact on the mcyt community, his character's role in driving many major plotlines, or if you like the old immortals hc, a lasting impact on the world throughout history. (If you like the old immortals theory, please consider pairing feldspar techno with olivine philza! Olivine is a green mineral, the most abundant in the upper mantle!)

A couple other notes: K-feldspar is pink because it has iron mixed into it, but it's named for the high concentration of potassium. Potassium is also known for: exploding! Also. It's PINK. But, generally I do tend to associate feldspars with Philza instead of Technoblade, because feldspars are what makes moonstone and labradorite, and I tend to associate moon and star mythos and symbolism with Phil.

Philza and muscovite:

I know I just wrote muscovite, but I was thinking of fuchsite, which is a chromium-rich muscovite!

I can't really put a finger on why I feel that muscovite fits Phil so well, but I think the micas suit him. Maybe it's something about how they used to use Mica to make windows (Muscovy glass, from Moscow, gives muscovite it's name!), and I feel that Philza's builds and character act as windows into rich worldbuilding. Maybe it's something about the fact that micas are made of many many layers and Philza adds a depth to each of his characters (and even literal layers with the colorzas). Muscovite is generally clear and reflective, while biotite micas can be dark enough to be black even in thin sheets. both suit Phil in my opinion, but the inclusion of alluminum in muscovite sometimes gives it a metallic sheen. It can be thin and transparent sheets, but it's still durable and versatile as a material. Maybe that reminded me of how people always see Technoblade as the warrior, but Philza has been known as a survivor for just as long if not longer.

Connor and Ocean Jasper:

I'm going to be honest. I know nothing about this guy.

Ocean jasper is blue. He's blue. What more is there to say?

Ocean jasper, or orbicular jasper, is a pretty rare stone! The main reason I assigned this to C!connor, other than the color, is that from the little I knew of his character, he was still somehow everywhere. That sums up my understanding of jasper pretty well too! It's a silicate mineral, defined more by its crystal structure than its composition, but some people still just call it chalcedony or quartz, and jasper is everywhere with lots of varieties! It reminded me of seeing all of C!connor's appearances with his normal skin and all the time traveler theories. The same Connor under different names, the same quartz under different names.

Niki Nihachu and Rhodochrosite:

This is the one I feel fits the best, actually! Yes I did initially think of it because it's pink, but Rhodochrosite is an extremely cool mineral and I think the fact that people think of it as "just pink" reflects perception of Niki's character compared to her true depth.

Just look at the versatility of it! From crystals to roses to speleothems. Rhodochrosite has been used for manganese, which is used in steel and aluminum alloy production, or to concentrate silver. In both cases the process is destructive and creates a lot of byproducts, which reminded me of the hurt caused to C!Niki through the revolution, and the way she was spoken over and ignored after. Another aspect of rhodochrosite is that it generally forms in hydrothermal veins. High pressure formation conditions to create this beautiful mineral reflect, to me, Niki's arc of finding herself again.

Ranboo and Snowflake Obsidian:

I think any obsidian fit's C!Ranboo well, but you know I had to choose snowflake obsidian because it's black and white.

Ranboo's fragmented memory made me think that a fracturing material would be a good fit, and obsidian has the properties of glass. It is also not lost on me that obsidian forms when magma or lava hit water. However, snowflake obsidian forms through the process of devitrification (vitri-, like vitreous, meaning glass-like), where glasslike substances become crystalline. The white material is cristobalite, a silicate material that forms at high temperatures. What this means is that snowflake obsidian is not as glass-like as other types of obsidian, just as Ranboo's memory loss is not exactly what it first appears to be either.

Dream and Gypsum:

Gypsum, in some forms called selenite, is a pretty well-known mineral. However, many of the forms are known under different names so people do not realize that they are all the same mineral.

Gypsum can form roses, clear selenite, reflective satin spar, the sands of white dunes, rock, crystals, and more. It's used in construction, to make chalk, to make buildings, to analyze mineral thin sections, to measure hardness on the Mohs scale, and to charge crystals by those that believe in spiritual properties of minerals. I see these many different forms as parallels to Dream's many faces on the server, real and perceived. Many different names given to different forms of the same person. I think the many used of gypsum also reflect the perception of Dream by the rest of the server. Gypsum is attributed power by some (is Dream the most powerful villian on the server?) and use by geologists and builders (Is Dream a way to get the revival book? Is he an ally?), but one of the main qualities is that it has a very low hardness, and is very easily broken. Is the role and name assigned to Dream, by others and by himself, more than he can fulfill without breaking?

Crystals for Apollo

Hello tumblr witches, wizards, Druids, and magical beings! I’m starting a new series today entitled “crystals of the gods”. I am a geologist and have been collecting minerals and gems for over 15 years, and seeing as how intrinsically connected to divinity and magick crystals are, I thought I’d look into what crystals are representative of the many gods and goddesses across the worlds pantheons. For my first post, I want to try and represent a god that although I do not personally worship yet, I am in awe of: Apollo/Apollon. Let’s begin!

• Citrine

Citrine is a gemstone of wealth and positivity, and nobody meets that standard in my eyes like Apollo does! They are full of joy and character, and shine like a beacon of yellow light that citrine encompasses so well.

• Brucite

A bit of a lesser known, but gorgeous mineral, brucites Scalenohedral crystal habit reminds me of the radiance of the sun! And it’s unbeatable bright yellow color is emblematic of Apollo’s connection to the lemon like color it holds, which facilitates much joy and pride in oneself.

• Pyrite

A mineral of subtle, but positive arrogance, and a touch of pride, pyrite might be called fools gold, but it’s not foolish at all! It’s incredible natural geometry is full of the character that Apollo radiates, and it’s literal reflective properties are a perfect metaphor for how the god represents hubris, but also character and personality that makes him so unique and adored!

• Muscovite

This powerfully flashy gem, a variety of Mica, is emblematic of Apollo’s more sensitive side that is often portrayed so beautifully, and often encompassed in acts of homosexuality. Muscovite is soft, only a 2-2.5 on the MOHS scale, but that’s not a negative thing! it’s color, and it’s personality, is among the strongest gold there is!

• Scapolite

Sharp and shiny, scapolite is the perfect stone for a glossy, muscular god like Apollo. It’s yellow hues are bold and sharp, and represent his strength in battle.

• Heliodor

Named after the archetypal god of whom he is a cultural descendant of, Helios, heliodor is the definite stone of the sun, and an ancient symbol of Apollo. Beryl was prized as a luxury to the ancient Greeks and Phoenicians, and heliodor was quite rare, this is an extravagant gift that he will surely be in awe of!

• Sunstone

This should be a no-brainer, but sunstone, a species of plagioclase feldspar, is somehow even more sunny than heliodor. It’s iridescent flakes of color remind one of the divinity of the sun, and it’s epithet, Apollo. Every Apollo devotee should offer the god some sunstone if they can get their hands on it!

• Amber

Warm and joyous, amber is perfect for Apollo. It’s honey like appearance, and beautiful deep warmth evokes Apollos radiance and pride. It is ancient, like they themself, and is a perfect idol of a god of sun!

• Topaz

Orange or imperial topaz, mined in the deserts of Utah and northern Mexico under a constant sun, is the domain of Apollo! It’s juicy colors are bold and rich, and remind one of Apollo’s intense personality.

• Peridot

Beloved by Cleopatra, mistaken by her for emeralds, peridot is like the spicier, more masculine version of emerald culturally. Often found in metamorphic rock around historically active volcanic sites, it’s no wonder that Apollo is attributed to its hot and spicy nature.

• Pyromorphite

In Greek mythology, Apollo was the slayer of Python, a massive serpent whom he dispatched of in a show of strength in Delphi. Pyromorphite, with its hopper like crystal structure resembling that of snake skin, paired with its serpentine color, is a great symbol of this historic accomplishment of the great Apollo!

• Tremolite

Similarly to pyromorphite, tremolites electric green color brings serpentine energy to a shrine dedicated to Apollo, and its a rare stone that feels like a perfect symbol to his awesome strength and power!

Well, there’s a good place to start! What crystals do YOU associated with Apollo?

[materialsscienceandengineering]

Materials scientists can now use insight from a very common mineral and well-established earthquake and avalanche statistics to quantify how hostile environmental interactions may impact the degradation and failure of materials used for advanced solar panels, geological carbon sequestration and infrastructure such as buildings, roads and bridges. The new study, led by the University of Illinois Urbana-Champaign in collaboration with Sandia National Laboratories and Bucknell University, shows that the amount of deformation caused by stress applied locally to the surface of muscovite mica is controlled by the physical condition of the mineral's surface and follows the same statistical dynamics observed in earthquakes and avalanches. The study findings are published in the journal Nature Communications.

Mineral Swag Round 3: Imagine the Collab Between These Two

Larimar is a variety of the mineral pectolite and is often a light blue color. Most larimar is found in the Caribbean, especially the Dominican Republic, and the blue color will permanently fade with sun exposure!

Lepidolite is a purple or pink lithium-bearing mica, so it has one direction of cleavage and this beautiful lavender color. However, the lithium is not what causes these colors! Manganese causes these colors. Another mica, muscovite, is also still in the competition!

These minerals are just really pretty colors. Especially together. The light blue and lavender is a good combo. But uh, fight to the death!

Planet Mercury: Correspondences, Magick & Astrology

Mercury is the planet closest to the sun in our solar system. It is also the smallest planet in the solar system, assuming you accept Pluto’s recent demotion to dwarf planet.

Mercury orbits the sun once every 88 days. It is bright, but difficult to see because of its proximity to the sun. Look for it in the morning and evening twilight.

The earliest known mention of Mercury is in an astrological compendium dating from 14th Cen BCE Assyria known as the MUL.APIN tablets.

The Babylonians called Mercury Nabu, after their messenger God.

The ancient Greeks called Mercury Stilbon, meaning ”the gleaming” and later called it Apollo when it appeared in the morning sky and Hermes when it appeared in the evening sky.

The name Mercury was given to the planet by the Romans who associated their messenger God, Mercury, with the Greek Hermes.

The Planet Mercury in Magic

The planet Mercury rules communication, information and networking, travel, trade, merchants, and commerce. Mercury rules Gemini and Wednesday.
