That ore you found is called redstone. The dust is used for many things in minecraft the pc version including a watch and a compass but unfortunately can't be mined to get idoms. I was dissipointed when I leaned it and my little brother keeps telling me to waste my diamond pick on the redstone to get stuff from it but I won't because I'm smart like that and hers not.:)
