Mr. McGill, you are correct. Bill would throw two heaping tea spoons of GA into a 1 oz. bottle of Pelican 401 red, his most favorite ink during his later years of scripting. It is the secret to scripting the finest hairlines. It took me, one of his students, years to handle ink that still. Unlike Bill, I liquify my GA. I take a pound of it, place it in a pan, start with a half-cup of water, and heat it (constantly stirring it) over a low heat on the stove. When the GA is dissolved, I decant it in a Talenti jar (eat and enjoy the Gelato, first). What I want to end up with after it's dissolved is a GA that is thicker than honey. When cooled, I add it to my scripting ink. The result is an ink as thick as Bill's, and you can script with it immediately. Bill would add the GA, then script with it the next day. He liked my idea and found that my ink was just right for him.
To keep the GA from accumulating mold, I add a bit of grain alcohol just to the surface it. It kills the mold, and the alcohol cannot be stirred into the ink: water and alcohol do not mix.
