The only method to smelt iron ore and quartz (to make glass) is to use a bloomery . Bloomeries reach temperatures higher than a firepit and can be used to smelt any ore, but cost significant quantities of fuel. The iron bloom , harvested from the bloomery, must be worked on the anvil to yield iron ingots, which can then be used to smith tools. This is a rather tedious process but this task can be mechanized using the helve hammer.
