Q: 10. Is this paper and the photos printed on it archival?

A: To some degree, but to make any fiber bond print truly archival, you need to use the recommended dilution and recommended time in the tray for the brand of rapid selenium toner you have.Use proper ventilation and gloves when handling selenium toner. It gives me migraines even with minimal dilution. Use a surgical mask over your nose and mouth particularly if you have asthma or are chemically sensitive. Art Paper is fun to use, but do watch your selenium timer closely! This paper will give purplish, chocolate brown to reddish shifts the longer you leave it in. Hope that helps.
