A strong, high density foam glass tile having a small pore size which can be used as a facade on both exterior and interior building walls. The foam glass tile of the present invention is strong enough that it can also be used as a structural member for a building. The foam glass tiles are very strong, and have a compression strength of 6000 psi (lb./sq. in.) or greater, and more particularly of 8000 lb./sq. in. or greater, and even more particularly of 10,000 lb./sq. in. or greater, and even more particularly of 12,000 lb./sq. in. or greater, and even more particularly of 14,000 lb./sq. in. or greater. These foam glass tiles will absorb more energy from an explosion, withstand higher heat and wind loading and other mechanical forces. The tiles of the present invention may have an average pore size of 1.0 mm or less, and preferably 0.7 mm or less, and more preferably 0.6 mm or less, and even more preferably 0.5 mm or less, and even more preferably 0.4 mm or less, and even more preferably 0.3 mm or less.
