"&lt;p&gt;Birchwood Casey\u2019s automated Tru-Temp finishing system uses a two-stage oxidation process to form a black magnetite finish on all iron and non-stainless steel parts.  The process is said to operate effectively at a temperature 100oF lower than other black oxide processes that require a temperature of 290oF.  The result is a protective black finish that is 0. &lt;/p&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
