    Hi Deb Tell the friend to mix it to a density that measures Baume on
    a hydrometer (this is the solution printmakers use and my supplier
    gives me the mixture he gives a local university printmaking dept).
    Or you can tell him you want a 67% solution. He should also be aware
    that when you mix ferric chloride and water there is an exothermic
    reaction (gives off heat) and it should be done under a ventilation
    hood. Ferric chloride is relatively benign as an etchant, but is most
    dangerous at the mixing stage. 

    I have been teaching etching with Ferric chloride for several years
    and have some notes on procedures and safety on my website if you are
    interested: Http://www.makersgallery.com/etch.html 

    Good luck with it Sandra In Owen Sound Canada with piles of snow by
