Has anyone dealt with refinishing historic wood mouldings and door trims 
scorched by fire so that the original shelac has blackened and bubbled?

Looking for suggestions of techniques for removing the damaged finish but 
preserving the rich dark patina of the original wood.

The scorching happened when a ball of flame, plasma-like, erupted through a 
hallway for a moment just as firemen arrived.   The fire started in a closet 
under a stair and had just burned through the closet door after reaching 
major temperatures inside.   Some of the wood is actually charred and will 
have to be replaced with appropriately stained new material, but much of the 
damage to the many doors and trims of the hall are simply blackened bubbled 
shelac.

With grateful thanks for any replies and references,
