I think that there is some confusion when folks see the term 'Nitre Bluing' and see the end result is what we know as 'straw' colored parts. Brownells sells chemicals for 'Nitre Bluing' and , while it is a heat process, it is also a chemical process in that is uses a 'salt' bath heated to a certain temperature to achieve the straw or blue colors. I am not sure but I believe that the temperature of the bath is the actually coloring agent and not the chemical used in the bath. So...it is really a trick question (heat or chemical).
