Happy birthday to chemist William Henry Perkin (1838-1907)! This #lino block print ‘William Henry Perkin Discovers Mauve’ is about how the British chemist & entrepreneur made the serendipitous discovery of the 1st synthetic organic dye: mauveine. ⁠
⁠
Perkins entered the Royal College of Chemistry in London in 1853 when he was only 15, studying with August Wilhelm von Hofmann. 🧵1/n

#Mice made transparent with a #dye used in #Doritos
Stanford scientists has found an agent that can reversibly make skin transparent without damaging it. #Tartrazine, a popular yellow-orange food dye called FD&C Yellow 5 is notably used for coloring Doritos. Hong’s team dissolved the dye in an aqueous solution and created a transparency-inducing lotion of sorts. It worked, because the dye reduced the difference in refractive index between water and lipids in the skin.

Zihao Ou, who helped develop this solution, holds a tube of food dye called FD&C Yellow 5.

The dye in Doritos can make mice transparent
'It’s not magic, but it’s still very powerful.'

A food dye that helps give certain sodas and snacks their hallmark orange hue renders mouse skin almost completely see-through in a reversible, potentially non-toxic research method that could transform medical and scientific imaging. Because of a counterintuitive fundamental physics principle, Tartrazine, also known as Yellow 5, can temporarily turn biological tissue transparent to the naked eye, as described in a study published September 5 in the journal Science.

Uh, don't try this at home...

Bobbing Boat

The canal has a leak, about 20 boat lengths from mine, under the railroad. There was a large puddle in the road.

A better photo would have included the canal on the right side.

Canal & River Trust workers are pumping liquid dye into the ground, and leaning over the fence to see where it leaks out.

"Don't worry, we'll fix it" said one of them.

I heard from a neighbour the leak has been there a while.

A rail bridge over a road and a canal (at right, not shown). In the foreground is the grassy berm between the road and the canal, and the towpath to the right, which runs alongside the canal. The water level of the canal is about 3 meters higher than the road. On the grass is pressure-pumping equipment and small barrels of dye. There's a makeshift fence made of boards. CRT workers are leaning over it, looking for dye flowing out. More CRT workers are standing below, in the road, looking for signs of dye.

Linocut portrait of William Henry Perkin (young, bearded Victorian man in a suit hold a flask up to his eyes) next a table with chemical glassware in silver. In his flask is a mauve fluid and the background has wide radial mauve stripes from a circle around the flask.

A little exploration, hand sanding to check grain fill, any more required? The face became flat ALARMINGLY fast. I'd been hoping for a lot more texture than has actually survived the sanding. Grain appears filled at least where I sanded.

Dyed a little to see how that'd go on the ash with the black contrast. I'm happy with the colour.

Seeing it in this state, now wondering about only dyeing the front, leaving sides/back black.

Hmmm, decisions. 🤔

Very close to a clear coat.

Guitar body, which has had some of black contrast paint sanding off, revealing wood colour with black paint stuck in grain. Some of that revealed wood has been dyed red.
Closeup of forearm carve on top of guitar, showing ripply grain, and contrast of black paint and red dye.
Guitar with half of front paint sanded back, before any dye involved.
Black painted guitar body.

Many experiments later (which won't be inflicted upon Mastodon) getting closer to something I like.

Koepoe Koepoe Merah Tua dye makes the colour I want to look at.

Tried on scrap, and sprayed a super heavy clear coat (runs/bubbles) just to see what it looks like under clear.

I also bought sanding sealer, so at some point must audition the whole process, sanding sealer, sand back, dye, clear coat.

I might go black paint as the grain contrast.

Guitar body with some dye samples on pieces of wood next to the body. There are some distinctive red, blue, and yellow colours, as well as some washed out indistinct colours.
Three containers of food dye, all different. Lemon Yellow, contains E102 with an ADHD warning (?!?!?!?). Koepoe Koepoe brand Merah Tua (Deep Red). Queen Blue Food Colouring.
Dye samples on pieces of wood, that have had a thick heavy automotive clear coat applied. Distinctive red, blue, and yellow colours, and now a little bit shiny. Left piece of wood is plywood, possibly birch, right piece of wood is some pine (Douglas?).
