I'm  dense with ratios.  I have certified 25-1 and need to make some 20-1.  How much tin is needed to make 20 lbs of 25-1 into 20-1?.

I need to have someone check my math here, but I think you need to add 3.2 ounces of tin to your mix, which should give you about 20 to 1, or 5% tin.

  That's what I came up with too, but I wouldn't consider your math checked yet.

PENTZ:
       20# of 25:1 has ABOUT 0.8# of tin in it, while 20# of 20:1 has ABOUT 1 #, so another 0.2# of tin, or 3.2 oz will get you close.   I say ABOUT, because 25:1 is not 4%, but is 1/26 tin, not 1/25.  Doesn't make that much difference, though.
