Newcastle Sandstone Flamed Top Mantels are a minimum of 2” thick and up to 5’ long. Mantels are made from one solid piece of sandstone, they have a flamed top, cut bottom and flamed sides. Flaming is a process that super-heats a cut stone face to produce a natural textured look. All of our mantels are custom cut to fit your specific application. Nothing finishes a fireplace like a Newcastle Sandstone mantel!
