Do a big melt(say ten or more ounces) and, from a hieght of about
five feet, pour the molten silver through a stainless steel sieve
into iced water. Use a very wide mouthed metal container for the
water - a bucket will be too narrow.
Then it's sort, remelt, pour, sort, remelt, pour.
Pretty soon you'll find the right height and speed to make quite
large quantities fairly fast.
