so, I just remembered that Mrs. Frederic has Neutralizer-tinted glasses (http://www.golive.com.au/television/television-2010s/science-fiction/warehouse-13/warehouse-13-mrs-irene-frederic-cch-pounder-screen-worn-glasses-multiple-eps-2), and remembered that somone from WH12 was involved in working Neutralizer into various materials for easier and safer handling of artifacts. However, I'm just curious as to how Neutralizer was worked into glass lenses, since from a cursory Google search, it's metal oxides that provide glass with color, discovered in the 8th century (using glass paint to dye glass was also mentioned, but I'm not sure if that would work as well or look as good from another cursory check, canonically or in reality). What do you guys think? I could do more digging, but I'm still not sure if I could find something that definitively points to which would be better in canon.
