Cheers Colin thanks for the info\ said:Paint it with a patchy light and dark brown, then apply a heavy matt black wash, when this is still wet sprinkle bicarb on the areas you want to look charred. When this is all dry use a thin black wash to soak into the bicarb to give an ash effect.Have a look at my 'crash' SIG diorama to see the effect in situ.
