Hello Everyone!
I’ve been dying to try out some polarization foldscopy!! and finally the wait is over! Just last to last week Laks Sir sent me some polarizing filters! I’d been collecting compounds from our Chemistry department and waiting eagerly for the filters to arrive. Here are the first few pictures I took using the cross polarizers

Urea Crystals

Magnesium Oxalate crystals

Trisethylenediamine Nickel II Sulphate And now finally something optically inactive! Nickel DMG

Ni-DMG Laks Sir had suggested me to try out a technique known as melt-recrystallization. I wanted to capture the crystallization happening through my foldscope. Here are some videos I recorded,

P.S: Watch the videos in HD. Theres an option available to change the video settings besides the Youtube logo.
Here’s the way I recorded the recrystallizatio
I prepared a dry mount of Aspirin. Then, I heated the slide with the help of a lighter to melt the Aspirin. Once it melted, I quickly observed it through my foldscope while recording the the aspirin getting beautifully recrystallized. 🙂
Hope you all like it!
Have Fun Foldscoping!
