    You asked the steps of my wire drawing procedure. I had explains it
    step by step. Please correct me. 

    Fist I collect silver and then put into a crucible. 

    Then the crucible is covered by charcoal and heat silver(I do not
    use any special cleaning methods only clean the crucible with a peace
    of metal). 

    After it is melted pour it in to ingot and try to keep it as a
    rectangle. 

    If It is not shape enough I hammer it to get the shape. 

    After hammering and get reduce to some extend (hammered three or
    four times) and I heated it till it gets red and dip in to water and
    hammer it to reduce the size. 

    When it reduces to a size where it can pass through the rolling mill
    I stop hammering. 

    Then I pass through the rolling mill till it's come to the size
    where it can pass through the draw plate. 

    Then I draw a wire through the draw plate to get the exat size. 

Thanks & Regards,
Indika Ranatunge.
