I am working to optimize conditions for growing Vitamin C crystals - and so far they seem to be best when I mix Vitamin C in deionized water and 99% isopropyl alcohol at a 1:1 mix - then air dry the slides for several hours. The variety of shapes and colours I see with a polarized light microscope is like nothing else I have seen in nature. I spent hours photographing the crystals.

Below are a few photos I took with 2.5, 5 and 10X plan Achromatic objectives using polarized light and sometimes a full wave plate. I used a Nikon D500 camera, ISO 100 and some of the pictures are very large panoramas of about 30 images. Some of the crystals have a silvery or gold metallic-like shine that resembles metal.

I have full details on how I prepare the crystals on my web site.

Cheers
Rob B

Hi Robert,
Great images and great inspiration.
Just made some and put in the fridge to grow. Using the fridge means longer time to crytalize, but the crystals grow "bigger"..

Thanks for sharing Very Happy

Beautiful work, thank you for sharing, Robert!

Have you tried 70% isopropyl alcohol instead of 50% isopropyl alcohol as solvent for vitamin C (did 50% work better for forming more photogenic crystals)?
