    I know that the hottest part of a torch flame is the tip of the
    inner cone, and that propane is not as hot as MAPP and acetylene.
    Even so, some of my sterling jump rings started melting. Clearly,
    there is more to know about torches and silver work. 

    --What kind of attachment is good for silver soldering? I used a
    disposable propane torch with a tip that is so old, Bernzomatic
    doesn't make it anymore. It was unused, but bought for making
    emergency repairs around the house. 

    --What should the flame look like? E.g., fluffy on the end or tight?
    Long flame or short? What color? 

    --Speaking of flames: How and why would you adjust the flame? This
    attachment only has the knob that controls how fast the gas comes
    out. 

    --What color is a "reducing" flame? 

    Perhaps this would be an appropriate article for the Beginner's
    Corner!
