Red Matter Blocks are extremely durable and can even withstand a nuclear explosion, similar to their lesser equivalent, the Dark Matter Block. However, while it may survive a nuclear explosion, it does not offer any blast protection, as the blast passes right through it. Also, it is possible for Red Matter Blocks to be melted by being in close proximity to a nuclear reactor that is overheating.
Red Matter Blocks cannot be pushed by pistons.
NOTE: Red Matter Blocks are only able to be converted back into EMC but not into 4 Red Matter.
Red Matter Block can only be mined by Red Matter Pickaxe.
While sprinting over the Red Matter Block, the particles of Glowstone Blocks will appear, rather than a special particle for a Red Matter Block.
