Lets see, salt prints were popular from 1839 to around 1850. A contact print process, exposures in direct sun of at least several minutes, sometimes hours. Then came albumen, from around 1850 to well into the 20th century. Again, a contact process with long exposure in direct or indirect sun light. Then came gas light papers--lets think about that--why would they be called "gas light." Slow papers, gas light instead of electricity. Remember, people had gas lights in their houses long before electricity came along. Silver chloride papers are still very slow, as any one who has ever tried to enlarge on Azo with an electric enlarger will attest. What about the other historical processes? Platinum/palladium, carbon, cyanotypes, POP, etc. are sensitive to UV light--i.e. the sun. The emulsions are around 1,000,000 less sensitive to light (and then it is UV) than current enlarging papers. Tintypes et. al. are sensitive to UV light as well. Glass negatives have to be printed on something else, see the above processes.

If you search *-bay, you can find darkroom safe lights which are alcohol lamps with red glass covers in the vintage section of the site. Again, used for gas light papers.

Check out the Alt Process section of APUG if you want to do prints without electricity. I have done (and continue to do) many of the historical processes. A word of warning, they are addictive. You are warned.
