I tested it with TNT and the basalt brick chamber had only 4 blocks remaining, while the obsidian withstood no damage. However, with industrial TNT, the basalt brick had only 1 block destroyed. I then tried a nuke in an obsidian chamber and 6 blocks remained. All chambers were 3x3 with 1 hole in the center.
