The Infusement Chamber is the crafting station used to create Infused Litherite Ingots from Molten Litherite Buckets and a potion as shown below. But be careful, this process is highly unstable and might cause a minor explosion. You can decrease the chance of explosion using Frozen Litherite Blocks surrounding the machine however this also reduces the processing speed, vice versa works with the Burning Litherite Block which increase the processing speed but giving it a higher explosion chance. Due to the unstability of the infusement process it's highly recommended that you do this away from structures you don't want blown up!
