Absolutely, if you want your China White to work properly you must collect a reasonable supply of aged Midwestern (preferably uncontaminated) saliva. This may seem a little unpleasant to use but you must harden yourself for the real rigors of engraving. You can see Mike Dubber using China White in some of his videos, he uses his own un-aged saliva, but he is a Midwesterner who is not young and is an experienced professional, so use caution if you intend to follow his example.
