Re: agar sizing
Hi Alberto (and Damiano), very interesting indeed. What about preserving the layer? Isn't agar-agar used to grow bacteria in glass dishes? (In laboratories.) Is it durable as hardened gelatin? (Probably gelatin also is vulnerable in humid conditions???) If it's durable then I would prefer it to gelatin because it leaves formalin and such out of the procedure. I can't say I like formalin much! Damiano, I don't think you need "proper jelly" in the paper -> something which makes the fibers less absorbent / less vulnerable to disintegration would be fine.
