(1.) Chald. attun, a large furnace with a wide open mouth, at the top of which materials were cast in (Dan. 3:22, 23; comp. Jer. 29:22). This furnace would be in constant requisition, for the Babylonians disposed of their dead by cremation, as did also the Accadians who invaded Mesopotamia.
(2.) Heb. kibshan, a smelting furnace (Gen. 19:28), also a lime-kiln (Isa. 33:12; Amos 2:1).
(3.) Heb. kur, a refining furnace (Prov. 17:3; 27:21; Ezek. 22:18).
(4.) Heb. alil, a crucible; only used in Ps. 12:6.
(5.) Heb. tannur, oven for baking bread (Gen. 15:17; Isa. 31:9; Neh. 3:11). It was a large pot, narrowing towards the top. When it was heated by a fire made within, the dough was spread over the heated surface, and thus was baked.

(See [225]OVEN.)
