			The controlled enviornment allows for greater efficiency and control over the reaction.

			== Uses ==
			Depending on the design, furnaces serve a multitude of functions and form the basis of a wide variety processes.

			The most common and important furnaces are used for food preparation and [[curing]].

			=== Food ===
			By [[cooking]] food, it can be more digestible for humans.

			The resulting smoke from the fire can be used to cure food more effectively for long term storage.

			Boiling can [[Sterilization\|sterilize]] water.

			=== Materials ===

			==== Curing ====
			Firing [[clay]] allows the vessel to become permanently set.

			This process applies to roof shingles, bricks, and earthware.

			Most drying processes can be accelerated with heat as the water evaporates faster<ref>https://en.wikipedia.org/wiki/Desorption</ref>.

			Borth can be farmed on industrial scales or manufactured in small batches.

			=== Good availabilty ===
			[[Alcohol]] is a good source of liqid fuels that offer some advantes over solid fuels but also carries additonal risk.

			Reliable combustion can be achieved with 50% to 60% alcohol content. To achieve this concentration, the alcohol needs to be [[Distillation\|distilled]].

			[[File:Chimney effect.svg\|thumb\|400x400px\|Pressure and airflow trough a chimney]]
			The basis of any common furnace type forms the chimney effect.

			Heat rises out of the chimney, any vaguely tubular structure will do, and pulls in fresh air from the bottom inlet.

			The fresh, cold air provides more oxygen and stokes the fire.

			By constriting the air inlet size, the rate of combustion can be ajusted.
