Would anyone know where I could get replacement tiles 4" x 2" approx replace broken ones on the hearth of a 1930s fireplace. Would appreicate any comments. I have tried the various places mentioned already on this site, but no luck. I may have to replace the whole lot as it would be hard to match them colourwise probably, but the thing is I haven't been able to find hearth tiles anywhere so far. Any comments appriciated. thanks.
