Il cloruro di sodio (NaCl) costituisce la base dell'acqua di mare ed è uno dei sali più comuni sul nostro Pianeta. L'uomo e gli animali superiori, essendo composti per oltre il l'80% di acqua salata, ne sono ricchi e ne devono assumere regolari quantità, soprattutto attraverso il cibo, per integrarne le perdite. Per questo non esiste organismo vivente superiore che possa fare a meno del sale. E per questo l'uomo, sin dalle epoche preistoriche, ha ricercato, prodotto e commerciato questo bene così importante, considerato prezioso quasi quanto l'oro, tanto da essere usato dai primi re romani per pagare i soldati (da cui il termine “salario”).

#Zed
Photo taken by Roby (please see the first comment) as she approached the fourth planet of the Zed Zolar Zystem on another mission to cause some UFO sightings. Ever since Earz's closest neighbour, the Rose Planet, had been made inhabitable, and a commercial shuttle service has been established, it has become the dernier cri for Earzlings to have a cottage on Marz, and to spend at least a few weeks there each year. Since Roby so enjoyed to cause UFO sightings on Earz – they always cause such a pleasant buzz, and they always guarantee such a huge TV, internet and newspaper coverage –, she had decided to expand her planet coverage.
As you know, Marz possesses two irregularly shaped moons, Phoebe and Deizel, and here you can see Phoebe with its characteristic protrusions facing Marz' west pole in the famous "Afternoon Tea" constellation that Phoebe reaches every day precisely at five o'clock in the afternoon, while Deizel is still hidden from the beholder's view, hovering over Marz' south pole (also known as "Marz' kitchen"). Unlike the Earz-like Marz, both Phoebe and Deimos consist mostly of NaCl. This breakthrough discovery made during the 2021 Marz mission "Perzeverance" – which had been expanded to the exploration of Phoebe and Deizel in 2022 after the Marz rover's AI had miraculously developed awareness, and was therefore able to conduct and expand self-reliant experiments beyond Marz' surface – was the final proof that Marz, Phoebe and Deizel originated from the Zechstein Zea (located in the European Permian Bazin which stretches from the east coast of England to northern Poland). It layed the foundation for the settlement of Marz under Perzy's (the name the Marz rover chose for it-, pardon herself) conduct.
So what do we have here: A backlit rose quartz sphere / ball – 2,5 cm / 0,98 inches in diameter –, and a side lit rock salt (Steinsalz) crystal which is 0,9 cm / 0,35 inches wide. I had to focus-stack both the salt crystal and the rose quartz, because anything stopped down further than f/4 resulted in a too prominent background (black glitter foamsheet), but with this relatively wide open aperture I never managed to get both the salt and rose quartz sharp in one shot. The salt crystal was held in place by tweezers (which I'd mounted on a clamp) – another idea had been to photograph the salt crystal only and make it look like a precious raw diamond held by a diamond cutter's tweezers for a close inspection of the "stone's" quality –, and I've retouched the tweezers with the clone stamp in Photoshop post-processing. Further processing was done in Analog Efex.

Versuch Nr. 8, mit dem veränderten Fomatone (batch 081048) einen farbigen Lithprint zu erzeugen.
Attempt No. 8 to produce a colour lith print using the modified Fomatone (batch 081048).
Fomatone 131
short exposure (30 seconds at f-stop 4+)
1st A+B+NaCl 30%+water 15+15+60+600 ml (NaCl works as a retarder, similar to Lith D or bromide) snatch point at 5:20 mins, when black has formed in the deepest shades.
2nd developer for colour, using the modified Lith A solution, which has already been presented on several occasions: A+B+water 30+25+600 ml plus 5 ml of D as an anti-fogging agent due to the ammonium salts contained in A, and 5 ml of Lith C (undiluted) to prevent the formation of semichinone, as the lith blackening had already been produced in the first developer.
Development time: 4 minutes. Longer development times (tested up to 6 mins) are possible in this developer because the pH level is within the non-critical range. Therefore, if the snowball effect does not already appear in the first developer, or is not present, it will not occur in the second developer.
Das geplante Kit könnte folgendermaßen aussehen:
Easy Lith A normal 250 ml
Easy Lith A modifiziert mit Ammoniumsulfit und Ammoniumchlorid 250 ml
Easy Lith B 500 ml
The planned kit could look like this:
Easy Lith A (standard) 250 ml
Easy Lith A (modified with ammonium sulphite and ammonium chloride) 250 ml
Easy Lith B 500 ml
Zur Erinnerung die Problemstellung:
1. Wegen der Änderung bei der Gelatinequalität hält das Fomatone dem recht hohen pH-Wert von Lithentwicklern nicht stand. Schon bei Entwicklungszeiten von 3 bis 4 Minuten können Strukturen entstehen, die an Marmoroberfächen erinnern, oder die als Snowballs bezeichneten hellen Flecken, die überall im Bild auftreten, vorzugsweise in homogenen Flächen.
2. Bei den kurzen Entwicklungszeiten, die erforderlich sind, um die oben genannten Fehler zu vermeiden, kann keine Farbigkeit entstehen. Es ist jedoch schon viel gewonnen, wenn wenigstens eine deutliche Lithschwärzung entsteht. Die fehlende Farbe kann dann in einem zweiten Entwickler mit geringerem pH-Wert hervorgerufen werden. Diese Lithentwicklermischung ist nur wenig oxidationsanfällig. Ein oftmaliger Gebrauch ist für einige Wochen möglich.
As a reminder, the problem is as follows:
1. Due to the change in gelatine quality, Fomatone cannot withstand the relatively high pH value of lith print developers. Even with development times of 3 to 4 minutes, patterns reminiscent of marble surfaces can appear, or the so-called ‘snowballs’ – light spots that occur throughout the image, particularly in homogeneous areas.
2. With the short development times required to avoid the faults mentioned above, no colour can develop. However, much is already gained if at least a distinct lith blackening occurs. The missing colour can then be produced in a second developer with a lower pH value. This lith developer mixture is only slightly susceptible to oxidation. It can be used repeatedly for several weeks.
I know this might all seem complicated to non-chemists, but I can’t see any other way to save this paper for the lith process.

It's supposedly translucent, but looks white enough to me for matching this week's Macro Mondays "White" theme.

Echo de menos los tiempos en que -por ésta época- hacía esquí de travesía.
Ahora en las islas lo tengo un poco difícil. A cambio puedo disfrutar del mar
y de "paisajes" como éste... aunque de momento no sean esquiables.

Now at the islands this is difficult to do, but I can enjoy the sea
and "landscapes" like this one... even I can't ski on them.

I was going to use this image for this week's MM challenge but it seems like there were lots of takes on salt so I decided to use the next photo of dashi granules instead. Happy Macro Monday!

Salt (NaCl) naturally forms cubic crystals, so when ground up tends to break up into roughly cube-like shapes.

Doesn't it remind you of the science textbook from your primary school? :)
I had a root canal treated last Saturday (super expensive, btw) and the dentist told me to gargle with salted warm water for the next few days to prevent the growth of bacteria. I did it last night and this is what I found today at the bottom of a glass. The photo itself is nothing special but I thought it was kinda cool.
