Minecraft wiki entry for Defeating_pyramids, associated text: Aside from the loot, these structures contain resources that you can get. For the desert temple, you get sandstone related blocks, terracotta, and the TNT in the treasure chamber. In jungle temples, there is cobblestone and mossy cobblestone. In the treasure floor, you can get redstone components, such as pistons, sticky pistons, dispensers, tripwire hooks, string, repeaters, and redstone dust, which can save you some redstone when building redstone contraptions. In the igloo, there is not many useful items, aside from the redstone torches, ice, bed, crafting table, furnace, cauldron, brewing stand, and the villager and zombie villager. The witch hut is almost useless as it only has a bit of wood. The only thing worth taking is the cauldron.
