RUBY-THROATED HUMMINGBIRD-08211712
Another trip back to Aug 2015 and Ruby Throated Hummingbirds in my garden. Late Aug and early Sept this year seemed to be the best time to capture them. This series is from one or two days in late Aug.
FOV: 6" wide.
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.

A Ruby-throated Hummingbird photographed in my backyard over the weekend, seen here feeding from a Petunia. First time this summer I have took to my backyard for these guys. Figures when I went out side all the clouds rolled in and chocked out all my light. Other then that, I was fairly happy with my first attempt of the summer.

MOC: Ruby Roadster. The profile is long (maybe a bit too long for the scale) and sleek - I think this is my favourite angle.

Have been after one with his crown up for a long while. A slow morning with the camera but really happy to get this guy. Heading to Ohio on Friday for some warblers. Fingers crossed!
