Chris, not sure of the brand or type of tile, I have some left over from when I tiled my foyer, I know it was called primitive tile an I believe it was hand fired. I,ll check with my brother in law who got the tile for me a few years ago. When you come up I,ll give ya a few to hit. Paul , it worked better than any Johnnystone that I ever tried but i really never hit much of it.
