As a Sexton in a church one of my duties was to dig the graves for for cremains to be interred. Having done 4 funerals I've seen 4 different people's remains. All were an off-white color and had a gravel type appearance with small pieces of what I assumed to be bone.
Are all cremains basically the same color, some form of white? If not, what would create a different color, perhaps a dark gray and partially pulverized and stuck to the plastic bag?
