Burial armour can be made at the back of the workshop's ground floor. Talk to Suak and he'll get Sten to show you how it works ("Suak is busy giving lessons"). Members can work with ingots of any kind of metal they wish (free-players may only use iron or steel ingots). Regardless of what metal you choose to work with, grade I ingots are used to make burial armour for miners; grade II ingots are needed for burial armour for warriors; and burial armour for smiths requires grade III ingots. The more valuable the metal you work with and the higher its grade, the more Smithing experience you will earn.
Iron Ingots require a smithing level of 70 in order to use the Furnace
Burial armour is a useful method of gaining experience as the ore for the ingots can be stored in the furnace directly next to the anvils, and all byproducts can be cast down the chute beside the furnace. Since these items hold no value, players can expect to see a loss from their experience gains. This armour cannot be alchemised.
You get exactly 10% more experience from smithing the assigned item.
Keep in mind this is without buying any boosts like Quick Learner, Budding Student or Master Student. Buying these would improve your total experience from assigned items by another 2%/4%/5%, for a total boost of 12%/14%/15%.
