<p>[QUOTE=&quot;dougsmit, post: 3323471, member: 19463&quot;]A question for cash students:&nbsp; Were the molds used for cash casting recycled in some way (pulverized into sand?) or was it necessary to dispose of all of that material as trash that could not be used a second time for coin manufacture?&nbsp; Years ago I did some sand casting (not coins) and we used the same sand over and over but we see molds for cash sold (usually broken pieces) which still bear designs.&nbsp; The article mentions animal bones making me wonder if these might have been crushed for lime to be mixed with sand for the molds.&nbsp; Has anyone studied how the ash were made?[/QUOTE]</p><p><br /></p>
