Rückschritt für den #Umweltschutz: Das Bundeskabinett streicht die Pflicht zur #Stickstoff- und #Phosphor-Bilanzierung in der #Landwirtschaft. Doch Wissenschaftlerïnnen warnen vor mehr #Überdüngung und schweren Schäden für Böden, #Wasser und #Klima: @christianschwaegerl https://www.riffreporter.de/de/umwelt/bundesregierung-beendet-stickstoff-phosphor-erfassung-landwirtschaft
Zu viele Nährstoffe in der #Umwelt verdrängen Blumenwiesen, lassen Gewässer umkippen und schaden dem #Klima. Doch auf Initiative von Bundeslandwirtschaftsminister Rainer müssen #Landwirte künftig nicht mehr bilanzieren, was sie freisetzen. Aus der #Wissenschaft hagelt es Kritik.

White LED Turning Purple: Analyzing a Phosphor Failure - White LED bulbs are commonplace in households by now, mostly due to their low powe... - https://hackaday.com/2025/05/30/white-led-turning-purple-analyzing-a-phosphor-failure/ #repairhacks #phosphor #autopsy
I made a sample tube today after just one day of spinning the jars of solventy phosphor lacquer. Oh goody is this a nice mix!
The pink is really nice- the white I messed up by running air through it too soon- the air blows the goop around like that. I used a puffy ribbon burner flame to burn off the cellulose - the tube goes all black and then goes all white again over the course of about 6 minutes.
I wanna make a bunch and then rent a big long kiln... overnight- the smoke is stinky and not good to breathe.
I made two new colors though! I might add a little more red to the pink to boost it up a little and get a little more powder in there, but I am excited to coat a few colored glass tubes hopefully tomorrow.
These mixes are nice for sucking up a tube- but I want to pour it in straight- then bend it so the inside of the circle is pink and the outside is warm white.
Further tests are necessary!
Spent some monies before tariffs started rolling in and got some phosphors (from the Netherlands).
Now I am making some new colors- a warm white and a pink. Mundy Hepburn was right- when buying phosphors- just get RGB... oh an maybe violet.
Gotta mix these on the ball mill for the recommended two days and then do some test coats- I sure am excited!
realistically I might do a test tomorrow. It will be nice to see how it moves and coats a sample tube.
It sure is coating the jar well after about 20 minutes. That is a 254nm quartz lamp for the argon mercury.
The nitrocellulose coatings are so effective! The chemicals are kinda nasty- but they evaporate rapidly and don't make phosphor waste that cannot be put down the drain.

I stayed late today to burn the binder out of all the hand pulled tubes I coated. Tomorrow I shall make a pretty doodle and (hopefully) see some fruits of my labour.
Fingers crossed for good shades of brown and pink light- a paradox I enjoy.
I have been noticing phosphor drips around the studio now. At first I was freaked out thinking they may release phosphor into the air- but they really just act like white paint. I cannot kick them up or scuff them.
Not sure if I should be laughing or terrified that my messes now glow pretty colors under a germicidal bulb?
Gosh- just look at that pink stripe! Some of my glassblower friends back their tubes with white glass. Sure that makes it look nice when its off... but I prefer the white backing to come from a glowing phosphor powder!
Sooo excited for tomorrow!
So - have just learned about Glow In The Dark Embroidery thread.
Someone please explain to me what *precisely* makes it work because I suspect micro levels of toxicity and so far my internet sleuthing cannot uncover any definitive answer..

Der Storeknuten in #Norwegen ist Hüter wichtiger Rohstoff-Schätze wie #Phosphor. Dieser wird aktuell vor allem nach #Europa importiert. Ein Bergbau-Projekt am Storeknuten könnte uns unabhängiger machen. Doch zu welchem Preis?
