Muv, American definition of Parchment Paper:

Parchment paperModern parchment paper is made by running sheets of paper pulp through a bath of sulfuric acid[SUP][1][/SUP] (a method similar to how tracing paper is made) or sometimes zinc chloride. This process partially dissolves or gelatinizes the paper, a process which is reversed by washing the chemicals off followed by drying. This treatment forms a sulfurized cross-linked material with high density, stability, and heat resistance, and low surface energy – thereby imparting good non-stick or release properties. The treated paper has an appearance similar to that of traditional parchment.
