Refractory blocks are important for the steel making process as no other currently available block can withstand the extreme heat necessary to produce steel . Refractory blocks come in three different tiers, all of which can be used to make the cementation furnace. All refractory brick blocks have a chance to receive damage per use of the cementation furnace smelting process, however, using higher tier blocks will reduce the amount that receive damage per use:

• Tier 1: has a heat resistance of 90% (1 in 10 chance to break).
• Tier 2: 95% (1 in 20 chance to break)
• Tier 3: 99.9% (1 in 1000 chance to break). (Tier 3 may actually have a heat resistance of 99.9% and thus a 1 in 1000 chance to break. This information needs verification.)
