Very nice! Did you grind up a pill?

Thanks for posting!

Beautiful shot.

How do you prepare the crystals?

I grind them up. Can’t find pure acetaminophen, and I haven’t found any way of separating the coating.

If you have access to alcohol (ethanol 96% is best but lower concentrations also work) you can mix it with the powder, stir, decant't the soluble part, filter through cotton and put in the freezer. You should see acetaminophen recrystallizing on the sides of the vessel. Scoop the crystals, wash them once with cold ethanol and after you dry them you'll end up with very pure acetaminophen that should form great crystalline patterns.

Thanks, Wes, I’ll try that,
