Chests are vanilla blocks that store items. A single chest can store up to 27 stacks of items or blocks and can hold up to 1728 blocks or items. A large chest is created by placing two chest blocks adjacent to each other, however, large chests cannot be created directly beside each other. Large chests have 54 storage slots and open as a single chest with six rows of slots. A large chest can hold up to 3456 blocks or items. They are used in multiple Tekkit recipes, some of which are shown below.
