Smelting is an important part of Survival:Beginnings.
Smelting is used to refine ores. This is important because the ores can't craft(except coal,sulfur, and stone) and would be useless kept as an ore.
How to smelt
Smelting is done by:
1st: Start a fire on something flammable using a lighter.
2nd: Place the ore on the fire.
3rd: Wait for the ore to turn into a metal.
Ta-da! You're done! And make sure that no one steals your ores when you're smelting.
The same thing can also be done with uncooked food items. Just be careful not to overcook.
Tip: It is recommended to guard your ores by holding out your sword whilst they smelt
