another way is to mix 1 cup of lime powder(from the garden area of stores) with 2 cups of water untill you get a thick gravy like consistancy and paint on with a bristle brush all over thick in some area and sparingly in others .. when it is completely cover use a spray bottle that has both stream setting and mist setting,, use the stream setting and spray in spots so that it runs off let dry slightly and use a med grit sandpaper and rub in random directions untill you get the look you want.. works preetty good..

This method looks especially good in terracotta that has raise deco around the base or rim of pot!
