Block of Alumite is a block added by Tinkers' Construct. Block of Alumite is primarily used as a storage block for Alumite Ingots but may also be used as decoration.
Block of Alumite cannot be crafted like vanilla Minecraft material blocks, but must be crafted by pouring 1296mB of Molten Alumite in a Casting Basin from a Smeltery.
They may be broken down by the use of a Crafting Table to produce 9 Alumite Ingots. With 4 Blocks of Alumite an Alumite-legged version of the Tool Forge can be crafted, which is purely aesthetic.
