How do you make your own handmade paper "acid free"? Answered
While there are a few archival sprays that reduce the degradation and yellowing of paper after the fact, that is not what I'm looking for. I'm curious as to whether I can add something to the pulp in the process of handcrafting my own paper. I've heard that adding calcium carbonate while it's still in a slurry can neutralize the acidity of the lignin in the pulp. If so, couldn't I just throw a few Tums in there? And how much per batch?
