<p>[QUOTE=&quot;desertgem, post: 1561296, member: 15199&quot;]Most chemistry classes mention alloys as rearrangement of the metals used into a different crystal structure than either one separately. This is why alloys generally have different physical characteristics than either separately, such as melting points, hardness, etc.&nbsp; Amalgams are when one substance such as mercury dissolves into (another) such as gold and retains it characteristics fairly closely, such as boiling point differences.</p><p><br /></p><p>p.s. added. Mercury also makes amalgams with sulfur crystals ( flour,flower) and that is why some mercury &quot;hazmat&quot; supplies are absorbent fibers coated with sulfur.[/QUOTE]</p><p><br /></p>
