    Yep, you have all convinced me that getting 24K maple leafs, or
    Krugarands is the way to go.    I plan to use the  Krugas for
    bezels, and  the  Maple leafs for  casting. My questions aRe:  

    l.  What is the best alloy to use for  casting which will not be
    brittle.  I want to alloy to 18 K.     

    2.  Can one do the alloying and casting at the same time---i.e.
    measure out the correct quantities for the desired alloy ( 18 K),
    and  correct weight for the model directly into  the casting
    crucible, melt them together, and stir, and then  cast, or does one
    need to make the alloy, then after it has cooled use it for casting. 

    3. If one has to make the alloy first,  cool  it  and then use it
    for  casting, what is the best way to turn it into grain---pour it
    into a bucket of  water???? or what.  4. Can one use fresh 14 K 
    casting grain and   the 24 K. Maple leafs to make 18 K.  I know that
    these are a lot  of questions,  but you guys  have always come to 
    my aid and  i will appreciate your experience and wisdom, and
    willingness to share.  Thanks- Alma
