    This is highly confusing to me.  Firstly, what is "19 or 20k weld"? 
    I have never heard of this grade of solder. Also, I thought that
    only lower karat golds could be used as solders on a given object. 
    Please help me to clarify this for myself.  I don't want to
    perpetuate any misinformation, if my previous understanding is
    erroneous.  Thanks.
