    John, THANK YOU! THANK YOU! THANK YOU! THANK YOU! THANK YOU! 

    In my classroom at SRJC I actually have a HUGE periodic table of
    elements on the wall. 

    It takes a while for the students to "get" that there are no science
    classes taught in our classroom and that metalsmithing involves
    chemistry, math, physics as well as passion, and patience. 

    You might consider adding Pewter to metals list? 

    Also, BTW - I have heard of cases of "metal Fume Fever" for as long
    as a week - one from extensive, continuous time (in one day)
    soldering 18k gold. - no cadmium in the solder, no fluorides in the
    flux - using Oxy-propane mini torch. Another from extensive,
    continuous time (in one day) casting sterling silver w/acetylene
    -Smith torch (Each metalsmith did visit Dr who specialized in
    occupational health) 

    These may be anomalies - but I thought they may interest you 

Cheers, Linda
