@nacredambition,
That imparted a pork belly laugh (well maybe a snigger)
It appears that parchment is made by gelatanizing the Pulp in the pulping process. They take a solution of sulfuric acid which dissociates the pulp and it reorganizes with a tighter surface bonding when its put into the paper frames (the running deckle).
Apparently modern parchment paper is just a denser form of paper which imparts its resistance to charring in heat.
NO animals are used in the process.
I used to do fake calligraphy pages of medieval books (like the Domesday Book) and the parchment I used was an animl skin based "paper"
They also make a "Bakery paper" which is used in commercial cookie baking . Bakery papr i gelatinized papar but is coated with silicone (I dont like silicone polymers traipsing around my body
