    Max muriatic acid concentration is about 37% and you can get at a pool supply store for pros. The stuff at walmart and home depot barely breaks 15%. I have heard that Ace carries the high concentration muriatic acid 30%+.

    Marko, the ferric may be more expensive, but it is a proven substance. My limited experience is that the stuff lasts long enough and you use so little of either liquid that your savings are not really going to be that much. Remember that 16 ounce bottle of ferric chloride actually makes 48-64 ounces of etching solution. The other thing about ferric is that it is gentle enough to replace stuff like lemon juice for a quick and dirty way to etch a hamon. You just dunk for like 10 seconds, neutralize, clean and polish a bit and repeat until you achieve the desired effect.

    This is what I found in the last couple of days.

    OK, so I will give ferric cloride a try. How difficult is to drain acid from a car battery? Have one on hand, but have to make a trip to RadioShack.

    Don't go burning yourself here, HCl and FeCl are both pretty nasty.

    Stefan just check the liquid concentration they sell in the store and use that percentage, if it is 37% as above stated, that is 37 g per 100 mL of water.

    Good to know. Fro some reason I thought it was ferrochloric.

    Sulfuric acid seems to be much more common in damascus etching than hydochloric acid anyway....
