I like to grow crystals at home, and it's one of the most beautiful crystals I've ever grown.

I made the potassium ferrioxalate myself by dissolving iron rust in cleaning acid (oxalic acid), and then adding potassium carbonate. Then, I evaporated the solution to get this crystal.

If you're interested in the procedure, I've written a guide here.

Too bad it's only worth 1 rupee though.

Dude growing rupee's when all you had to do was smash some pots.
