If the DM allows the characters to simply scoop up the loose treasure, then he has not fully recognized nor considered the effects of the magical energy released during the battle. Reviewing the temperatures produced by a fireball, an average of about 1,600°C, it is seen that the heat is sufficient to melt copper, gold, tin, and even platinum, to some degree, as described in the table appearing later in this article. In an impure state, as would be the case with metals of a medieval society, metals melt at considerably lower temperatures perhaps as low as 100-400°C less. Silver, which has a pure-state melting point of 961°C and boils at about 2,000°C, becomes a liquid at the temperatures associated with exceptionally hot or very large and hot fires. If the heat persists for any length of time, as with a fire storm or flame strike spell, this liquid has a chance of flowing and coming in contact with other metals or objects, fusing the lot together upon cooling. Therefore, if any of these metals are present along the extreme edges of a pile of treasure and are exposed to these fires, the result is a melted, fused, and utterly deformed outer layer which, after cooling and hardening, requires a concerted effort on the part of the characters (with the appropriate tools) to chisel apart into manageable chunks.
