    Iodine Starch test

    I wanted to try the Iodine Starch conversion test. I bought Iodine Tincture 2% U.S.P. (first aid antiseptic) from the local pharmacy. Never really got it to work. Even prior to sparging, the color stayed the same. Am I using the wrong stuff?:drunk:

    Iodine Starch Conversion Test

    Forgive the potentially ignorant question. I'm wanting to do an Iodine test for to check for proper starch conversion. Is just straight Iodine what's needed, or is there a certain kind that is produced specifically for the brewing industry? Thanks.
