Had a 'request' to show some of my Photomicrographs taken at University College London where i was a Scientific Photographer for 8 years . I think THIS was Ascorbic Acid by Polarised light
I've grown some Ascorbic acid crystals, it's amazing the variety of forms you can get by varying the speed that the crystals grow. Some grow so fast that you can watch it happen in real time. Thanks for sharing these!
