@thereisnocat Do you know the wavelength of your UV light? If your lows aren't getting dark enough in such a long time, it might indicate your UV light's wavelength isn't optimal. 365nm is supposedly best, but I found it harder to find decent options. So mine are 385nm (40W) and 395nm (200W) and the corresponding exposure times and distances are only: ~1:45min (4 inch) and ~2:40min (16-20 inch). For the latter, I initially also used a sheet of paper to diffuse the light more (for larger prints), but that extended the exposure time to ~17mins for not any noticeable difference...
(Btw. This is all for kallitype, but should equally apply for salt)

New video! I'm taking a look inside my very inexpensive EPROM eraser and I'm making some modifications.

I'm cleaning out a relative's house and one of the fun finds has been glassware that glows under UV light and thus might contain uranium. But fluorescence isn't especially bright so I have to find a Geiger counter to confirm. #uvlight #fluorescence #uranium #glass #glassware #annagrün #annagelb

I've recently learned that some glassware contains uranium dioxide and will glow under ultraviolet light. And that they're collectible. For giggles, I used my UV Beast to illuminate some bowls at a house I'm cleaning out. They are not at all yellow/green in normal light. Are they glowing enough? #uranium #fluorescence #uvlight #physics #chemistry #glass

Scientists developed a method for purifying #proteins from cell extracts or cultures using short-wave #UVlight, which is invisible to humans. The technique is more efficient and gentler than previous methods: http://go.tum.de/385699

Reindeer vision may have evolved to spot favorite food in the snowy dark of winter
https://phys.org/news/2023-12-reindeer-vision-evolved-favorite-food.htmlReindeer and the quest for Scottish enlichenment https://journals.sagepub.com/doi/10.1177/20416695231218520
"#reindeer eyes change between summer and winter... they see the winter world as a shade of #purple, similar to how a person would see a room with a black light... the answer is tied to what #UVlight doesn't reflect from—C. rangiferina and other bushy #lichens."

Today I learned something about UV light, after 20 years of using biosafety cabinets level 2...
UV light, only when the cabinet window is closed, is used whenever we want to be sure that the following experiment won't be contaminated.However, some major authorities *advise against it*, mainly because of the risk of irradiating the user and because it is no substitute for proper cleaning (which I knew). Indeed, when it's dirty, microbes are shielded from decontamination.
