dissolve mineral and crystalized the minerals is another way to prepare the specimen for polarized light microscope examination.  Yesterday, I dissolve several common ingredients for food seasonings and put a few drops on the slides to allow them to dry: table salt (Sodium Chloride), Sugar and Alum hydrated potassium aluminium sulfate.  I also drop a few drops of methylene blue.  Today they are all pretty much dried out – The sugar is still somewhat sticky but I can clearly see the sugar crystals in snow flake shape.

 The color of the sugar crystal shows richer color when I adjust the gamma correction.  The loss of color must have been caused by the manual shooting mode.

The delicious fruit, fig, is actually a flower.  After long hot and humid summer, my brown turkey fig is finally in full production.  I can usually harvet half dozen a day.

This is my first attempt to use Canon EOS T1i with my Ample Scientific SM Plus-13 stereo microscope.  My canon adapter only accept the 23 mm eye piece port so I added the adapter ring from the Tucsen relay lens.  It is a little bit loose but it worked out just fine.  The camera settings: ISO 100, 1 second exposure and auto white balance.

Yum, I can smell the sweet nectar of the brown turkey fig.
