    Working with a Little Torch, I use a tip with six orifices (for
    propane/oxygen) to melt the metal (Dave, Tim, John and others here,
    thank you again for your information). This is certainly a big
    improvement, but it remains problematic to melt 45 - 50 gr. of
    Sterling. Funny I was told that the melting tips was to be used
    acetylene/oxy only. Could someone confirm this? Dear Jon, I have used
    propane for anything that acetylene will do (for 30 years)! To work
    on platinum ( or melt large quantities of Sterling), I boost the
    poundage on my tanks - especially the propane (20-25). 
    Good luck, georockman
