This experiment demonstrates the shift in color from yellow-green to blue-green of minerals containing the uranyl ion in conjunction with carbonates.
Uranyl nitrate was combined with NaCl and recrystallized on the glass rod. Behind it is a specimen of meta-autunite from the Daybreak Mine in Spokane WA, USA. Meta-autunite is a uranyl phosphate mineral.
Uranyl nitrate solution (0.25M) was combined with a sodium carbonate solution (1.25M) and was used to rehydrate some DAP Plaster of Paris mix which was set in a square mold.
Initially (when still wet), there was no fluorescence but after the calcium sulfate re-hydrated (and the mix produced CO2? bubbles), the resulting plaster fluoresced a bright blue-green, typical of carbonate based uranyl minerals. Behind the plaster square is a specimen with a coating of andersonite from Yellow Cat Mesa in Grant County UT, USA. Andersonite is a hydrated sodium calcium uranyl carbonate.

Unknown Fuji B&W film@ 100 ISO.I think it is orthochromatic motion picture or technical film (there are any markings near perforation).

For me, fashion is a form of art. I wanted to take the time and experiment with some styles and colors to se what works and what doesn’t. Feel free to comment on what styles you think work best 😃
You're taking my breath away ;-) But I'm happy to help with your Bone Marrow experiment! asc-csa.gc.ca/eng/sciences/marrow.asp

What???? What???? What???
Here is the back story: I bought 19 boxes of doll clothes gambling that their would be some awesome vintage clothes and there ARE!!! BUT, yes there is a but, :( I observed the boxes were moldy. The seller said yes but the clothes were all in plastic bags. With the exception of a few clothes here and there the doll clothes were in plastic bags with one other HUGE exception. NONE of the vintage Barbie clothes in two different boxes were in plastic bags. One box was no problem as the mold had not penetrated the box BUT, oh yes another BUT, the other box had more mold than any of the other 19 boxes. It had penetrated the bottom, entered the inside of the box and contaminated the clothes!!! Oh what a heartbreak. I blew as much mold as I could off with air from an air compressor and stuck them in a plastic bag. I googled clothes and mildew where I read from several sites that borax kills mold and gets rid of stains in clothes. Also that it was good for dumping down your sinks. NO WAY!!! Crystals in my pipes??? I get ahead of the story. I thought it would be a good experiment to try the borax on some Calico Critters that had never been removed from their boxes BUT mold had also penetrated their boxes. Maybe borax would work on cloth but CRYSTALS??? Is it a chemical reaction to plastic? Some plumbing pipes are plastic!!! Information said borax worked well in dishwashers but there is plastic in dishwashers. Maybe I should have added detergent to the borax solution. It all makes my head hurt. In conclusion the borax did NOT work!!! I had to soak the critters in really HOT water to get the crystals to dissolve and the mold was still there.
A concrete pump operator finished work here at this location and begins folding down to relocate. This construction site is part of highway Interstate 69 In Rosenberg, Texas, near Houston. In support of America’s international trade routs, when finished, the highway will stretch border to border across America and connect Mexico to Canada. The project will take decades to finish.

Another shot from the first roll through my Agfa Record pinhole camera, I will be experimenting with this a bit.
I have experimented with this image to see if it succesfull to the Flickr audience.
I've found that I have slowly adapted to apprieciate the art of abstract photography, but I feel I haven't yet quite mastered the art. I would be hugely greatful if you would leave a comment to give your opinion on how the photo turned out. Thanks :)
Experimenting with long exposures. I need to figure out how to prevent the lens flare, more time behind the lens is needed.

This experiment demonstrates the shift in color from yellow-green to blue-green of minerals containing the uranyl ion in conjunction with carbonates.
On the right ~15mL of calcined garden gypsum (rinsed) was combined with 7.5mL of a boiling solution containing sodium chloride, sodium carbonate and uranyl nitrate in an aluminum form. The mixture released much gas (CO2 ?).
On the left ~15mL of DAP Plaster of Paris (containing CaCO3) was combined with 7.5mL of the cooled previously mentioned solution after it had been treated with HCl to remove the carbonate ions. The still acidic solution reacted with the CaCO3 in the Plaster of Paris mix and was mostly neutralized by the CaCO3 becoming CaCl2 and CO2 gas (and H2O). The mixture was left to set in a plastic form.

for a laugh you must watch this video sent to me by my dear friend Tao of Jonathan it is simply adorable and a guaranteed smile!
She has not been on Flickr in a while, so some of you may not know my sweet companion of fourteen years, yes this little beauty is fourteen years old..
We have welcomed many years together, and will do so again this New Year's Eve, with maybe a friend or two who may drop by for an egg nog.
Notice her littlefblack heart on her nose. It was not there the first year of her life, and one day it just appeared, honestly.
Have a great day,
