You’re very welcome Dr Paul. What I love about Comic books conservation, is that it isn’t that dissimilar to documents conservations and a lot of the work has been done for us, we just need to find it! And this is a prime example.

Very interesting Peter.

It’s a good product. They use it in the paper industry alongside sizing agents. Works wonderful on getting the fine particles in solution bonded to the fiber and removing small solutes from water. So a great addition to use when contemplating natural or artificial pulp coloring.
