“Then henceforth it should be slender, bent, and gnarled,
With blossoms forming a cross, forever marled.”

“Four slender petals bowing, tips streaked with red,
A reminder of the blood our Savior shed.”

“And where the bloom’s center shows a thorn‑like crown,
A sign that love and sacrifice forever hold us down.”

Rayleigh scattering

Green eyes: "Curious blend of light brown pigmentation, a yellowish lipochrome pigment, and a splash of Rayleigh scattering."
In an article for Owlcation, biostatistician Edmund Custers broke down this strange phenomenon. Basically, "green" eyes only contain a small amount of the brown pigment called melanin. In the absence of a lot of melanin, Rayleigh scattering happens. Rayleigh scattering is when, as Custers explained, "longer wavelengths of light pass straight through the eye, then they are absorbed at the back of the eye." He added, "Shorter wavelengths (blue wavelengths) are reflected and randomly scattered by the opaque layer of the iris." Brown eyes, on the other hand, absorb light because they contain more melanin. Although Rayleigh scattering is also responsible for making blue eyes, well, blue, green eyes are especially unique because of this "curious blend" of blue wavelengths and yellowish pigment.

Graphite vs Diamond

Diamond in the rough.

I am often not able to post some of the stuff I am working on for reasons, but the process can be interesting. I am very excited to start using this graphite putty. I can change any paint into a graphite paint, which gives the appearance of graphite pencil but is applied as a water-based paint.

As a Geologist, I find graphite a very interesting mineral-- although chemically quite simple. Graphite and diamond are both chemically identical--made entirely out of carbon. The difference between them is caused by different molecule arrangement creating very different crystal structures. Diamond crystallizes in the cubic system, tetrahedral, but graphite crystallizes in the hexagonal system, planar. Diamond is clear and transparent, but graphite is black and opaque. Diamond is the hardest mineral known, but graphite is one of the softest. Minerals which have the same chemistry but different crystal structures are called polymorphs.

This one is still sitting on the canvas stretcher… think it needs a final reveal

Red Skis—quick 1 hour painting

Snow is made up of ice crystals and appears white to the human eye because of how the transparent crystals reflect light.
