I report too much on pharmaceutical manufacturing quality, but come across stuff like this ... very rarely.

Yeah, iron oxide pigments have been synthesized by the absolute sh*t-tonnalades for hundreds of years! I think they are so f*cking cool, including the whole history, from mining to synthesis.

Used for at least 25,000–30,000 years in prehistoric cave paintings, yellow ochre is one of the most dramatic yellows for interior painting — the most, IMHO.

Yellow iron oxides, which appear almost brown in the raw, when mixed with white are converted into a brilliant and radiant warm yellow, unlike other non-toxic yellow interior pigments — like benzimidazolone, diarylide, or Hansa yellows — which are colder, sometimes even greenish dyes.

In previous lives, I had home improvement businesses for some 20-30 years, and used no other yellow.

In fact, I used no other orange, no other red, no other brown, and no other black pigments than those derived from iron oxide, coined by industry as Mars pigments.

Iron oxide covers the entire spectrum of warm colors from yellow, through orange and red, to brown and black. These pigments are actual microscopic particles of the Earth.

I have a mythical belief that the Sun's light and the Earth's magnetism interact with these pigments, and reflect light like no others — electron spin, polarization, IDK. It's just different.

Unfortunately, the only blue pigment approved for interior painting in the US was thalo blue. I'm not sure what's going on with non-toxic interior blues, nowadays.

Thalo blue is not a particularly pleasant blue, to me. It looks like plastic feels — unlike manganese, cobalt, or French ultramarine blues, for example. Though not FDA-approved for lip products, French ultramarine blue is generally considered non-toxic.

Rust is something hybrid, something that grows and can overgrow. When I look at glass it pretends not to move, but when I look away it always feels like it starts to drip and leak. In my art practice, I have worked a lot with rust, which all started with my fascination for colors and pigments. For six years, I have been making my own pigments from plants that I pick in my garden or from wild plants, which I then use to dye organic fabrics or paint on paper. I also like to work with ceramics and glass, but I was never able to use these pigments in ceramics or glass because the high kiln temperatures - between 800˚C and 1240˚C - burn the pigments and turn them black. Rust, being inorganic, doesn’t get burned in the glass oven; instead, it transforms. So, it turned out to be applicable to both ceramics and glass. I search for rusty items as I walk and soak them in water as soon as I come home. The longer I leave the rusty finds in water, the blacker the rust becomes.

Just some fun little flowers I made with my beginner wheel students during our handbuilding session. I used some oxides and frog pond clear glaze to finish them.
