Experimenting with XPAN style cropping in the Fuji GFX50R. Processed in DxO PhotoLab 6 and converted to B&W in Silver Efex Pro.
Three recent experiments - mostly relating to needle felted jewelry ideas.
I've been toying with the idea of doing a steampunk necklace and having seen that octopi often show up in steampunk I made one. Flat on the back, dimensional in front. Doubt that this particular piece will work with the gears I bought.
Beads and a Cabochon - I've used silk before with my Merino fiber and I know that it adds a luster and reflective quality that the wool lacks. The beads and cabochon are very firmly felted.

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.

Much appreciation to Gordon Czop for the uranyl nitrate.

i like to experiment with my hands, observe them, observe others', to see how they affect people in a touch

This experiment was an attempt to recreate the fluorescence of chromium activated corundum (aka 'ruby'). Aluminum hydroxide was mixed with 1-4 drops of Cr(III) oxide in a basic solution. This was placed on a small amount of aluminum sulfate in an aluminum foil container and a bit of water was added.
The sample was then heated, first with a propane torch until the water was removed and then with a MAPP gas torch until the aluminum sulfate expanded into foam, trapping the aluminum hydroxide which was calcined into aluminum oxide by the torch's flame. (at least that was the plan)
Shown also is a natural ruby from Mysore, India.

This was a 2xNDF and I think it has brought out the sky and strengthened the colours.
The edges of the main trees are supposed to be blurred as it was windy and that's what I was trying to capture.
More experiments another day, today is very showery and I had to put the kit away once, dry it all off and then get it out again.

In this experiment, the color of the liquid in the flasks will change to yellow if you blow in the straw. This student tests whether an aquarium bubbler will also cause the color change. For more science experiment ideas, see www.biologycorner.com

so I discovered that you can use an oil pastel as a resist. even cooler is that you can scrape off the oil pastel to reveal the color underneath. eyes and mouth were done this way. i then went back and added outlines with sharpie.
With the wig frustrations I've had with my Puki, I try something I read Spampy do. I've done this before with my tinier elfdoll but directly to a spare head cap. I didn't think it would work - peeling the plastic wrap off from the inside but it works. My top isn't great but this is the first time my Puki has had a wig that fit and fit her face.
No worries, you wig makers - No way would I try to sell these - you guys make amazing wigs and I have enough to do and I'm betting these fall apart with a good dose of water. The mohair I use is also for cloth dolls and such, nowhere near the quality mohair wig makers use so cutting hair from it isn't painful at all.
