Ores are needed to player for progress further in Terracraft and are usually mined with pickaxe and are able to be smelted with a furnace. There are overall 13 different ores: coal, tin, copper, Iron, lead, silver, gold, diamond, emerald, lapis, redstone, quartz and ancient debris.
This is still W.I.P so there may not be all ores as the guy who wrote this is only barely started the game
