Day #3 of Parchment Conservation - Part 2 - Surface Treatment In the second half of today's workshop, we experimented with different surface treatments for parchment. These would have been applied to finish the surface for writing. Different techniques create different finishes that are hard, soft, shiny, or matte, depending on the desired use and look of the finished product. For a soft finish, try bread baked with ground glass (or sandpaper, if you don't have the former lying around). For a hard surface, try egg white, dried in the sun and polished to an even sheen.
