Step 6Purification with activated charcoal
In this next series of steps, we'll use granulated activated charcoal to clean up any large molecules that could interfere with our desired crystallization later.
Stop boiling the solution and let it cool to at least close to room temperature. If you're impatient, you could cover the pot with a lid and set it in a sink full of cold water and ice (or if it's cold enough outside, cover it and set it outside for a while).

I found a hand warmer which contains iron powder, water, salt, vermiculite along with the activated charcoal. It will work?

Um... not sure what you're asking. Are you asking about the activated charcoal? If so, *no* - the salt will be a problem. Activated charcoal can be purchased cheaply from pet suppy stores (ones that carry fish and fish supplies).

Depends on what it is. If it's *activated* charcoal, it'll work just fine.
