Anthracite

Had an argument today with the tile&floor-man. When I was in the flat last week it looked like the "Fugen" were not black as I had ordered. You know the stuff they put in between the tiles on the floor. If I have black granite floor, I certainly do not want grey stripes around it, I want black. Today he assured me they put anthracite on it, which I interpreted as grey but he assured me it is black. It was "only because it's dusty now". Hmmm. Going there on Friday to inspect.
