Put the iodine tincture in a shallow glass dish; let it evaporate at room temperature; what's left behind is a thin film of crystalline iodine that you can scrape off - note: iodine like chlorine is very reactive; that's why it's used as a germicide - were you to put a candle under the dish you would see the iodine sublimate (go directly from a solid to a brownish gas). Iodine does not come in a powder form, but you can get USP (United Stated Pharmaceutical Grade) Iodine crystals at any pharmacy with a doctor's prescription.
