Re: [BKARTS] 8 Century Psalter found in a bog in Ireland

Hi Myrna,

Neither parchment nor vellum are tanned. It is just dehumidified and 
scraped skin. The difference between parchment and vellum usually is the 
thickness and the surface. There are some very rare manuscripts, written 
on a vellum made of  stillborn animals, which is even softer and thinner 
than the normal vellum, but it is still made without tanning process.
In the National Museum of Cairo you can find a scroll of tanned 
"parchment", it is a mixture of leather and parchment, but it dates from 
about 2000 B.C.
