    Unfortunately it is the nature of the palladium to absorb both
    hydrogen and oxygen. Both of these gasses can be held in greater
    amounts in liquid palladium than in solid palladium so when it
    solidifies the gas comes out of solution and forms bubbles these
    bubles are the porosity you see in solder joints. A neutral flame
    and high temperature flux will help with this problem.
