Etymology: "Furnax" is an unusual English word: it is an obsolete or rare variant of "furnace," first recorded in the 15th century in English. It descends from Old French "fornaise," which came from Latin "fornax," meaning oven, kiln or furnace. The Latin word itself is linked to "furnus," an oven, and probably to the verb "formus," meaning warm, which points to an ancient notion of baking and heat rather than of metal smelting. The "-ax" ending is the surprising part. English speakers tended to treat "furnace" as the normal form, so "furnax" survived mainly as a learned, Latinate spelling used in some older writing and technical contexts, where it was meant to echo the classical source more closely. Its meaning has stayed close to the original idea of a heated chamber, though it is now seldom used outside historical or deliberately archaic prose.
