Thanks SDS for the science lesson. I remember Molybdenum as being on the periodic table of elements from my HS/College science class days but I have never seen or dealt with it. I wonder how they got the shortened name as noted above from the original element name? Anyway, back to the point. I think it is a pretty good mask. It is my number one and I only keep the Honig's as a back up.
