From Team Fortress Wiki
The Pile Of Ash was an item that could be crafted from four incinerated remnants of the mysterious treasures. When it was used, it opened identically to a Mann Co. Store Package and yielded a single Scorched Crate and/or one of the items introduced in the Pyromania Update (besides the Escape Plan). This item was removed from the game in the July 11, 2012 Patch.
