Furnace like a brick-kiln (Dan. 3:15-2715Now if ye be ready that at what time ye hear the sound of the cornet, flute, harp, sackbut, psaltery, and dulcimer, and all kinds of music, ye fall down and worship the image which I have made; well: but if ye worship not, ye shall be cast the same hour into the midst of a burning fiery furnace; and who is that God that shall deliver you out of my hands? 16Shadrach, Meshach, and Abed-nego, answered and said to the king, O Nebuchadnezzar, we are not careful to answer thee in this matter. 17If it be so, our God whom we serve is able to deliver us from the burning fiery furnace, and he will deliver us out of thine hand, O king. 18But if not, be it known unto thee, O king, that we will not serve thy gods, nor worship the golden image which thou hast set up. 19Then was Nebuchadnezzar full of fury, and the form of his visage was changed against Shadrach, Meshach, and Abed-nego: therefore he spake, and commanded that they should heat the furnace one seven times more than it was wont to be heated. 20And he commanded the most mighty men that were in his army to bind Shadrach, Meshach, and Abed-nego, and to cast them into the burning fiery furnace. 21Then these men were bound in their coats, their hosen, and their hats, and their other garments, and were cast into the midst of the burning fiery furnace. 22Therefore because the king's commandment was urgent, and the furnace exceeding hot, the flame of the fire slew those men that took up Shadrach, Meshach, and Abed-nego. 23And these three men, Shadrach, Meshach, and Abed-nego, fell down bound into the midst of the burning fiery furnace. 24Then Nebuchadnezzar the king was astonied, and rose up in haste, and spake, and said unto his counsellors, Did not we cast three men bound into the midst of the fire? They answered and said unto the king, True, O king. 25He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the form of the fourth is like the Son of God. 26Then Nebuchadnezzar came near to the mouth of the burning fiery furnace, and spake, and said, Shadrach, Meshach, and Abed-nego, ye servants of the most high God, come forth, and come hither. Then Shadrach, Meshach, and Abed-nego, came forth of the midst of the fire. 27And the princes, governors, and captains, and the king's counsellors, being gathered together, saw these men, upon whose bodies the fire had no power, nor was an hair of their head singed, neither were their coats changed, nor the smell of fire had passed on them. (Daniel 3:15‑27)).

Concise Bible Dictionary:

Furnaces were used for various purposes, as smelting the crude metal, and for crucibles to refine the metal; for lime and bricks; and as an oven (Gen. 19:2828And he looked toward Sodom and Gomorrah, and toward all the land of the plain, and beheld, and, lo, the smoke of the country went up as the smoke of a furnace. (Genesis 19:28); Ex. 9:8, 108And the Lord said unto Moses and unto Aaron, Take to you handfuls of ashes of the furnace, and let Moses sprinkle it toward the heaven in the sight of Pharaoh. (Exodus 9:8)
10And they took ashes of the furnace, and stood before Pharaoh; and Moses sprinkled it up toward heaven; and it became a boil breaking forth with blains upon man, and upon beast. (Exodus 9:10)
; Prov. 17:33The fining pot is for silver, and the furnace for gold: but the Lord trieth the hearts. (Proverbs 17:3)). The fiery furnace in Babylon must have been very large for four persons to have walked therein. It may have been the furnace they used for their bricks (Dan. 3:6-266And whoso falleth not down and worshippeth shall the same hour be cast into the midst of a burning fiery furnace. 7Therefore at that time, when all the people heard the sound of the cornet, flute, harp, sackbut, psaltery, and all kinds of music, all the people, the nations, and the languages, fell down and worshipped the golden image that Nebuchadnezzar the king had set up. 8Wherefore at that time certain Chaldeans came near, and accused the Jews. 9They spake and said to the king Nebuchadnezzar, O king, live for ever. 10Thou, O king, hast made a decree, that every man that shall hear the sound of the cornet, flute, harp, sackbut, psaltery, and dulcimer, and all kinds of music, shall fall down and worship the golden image: 11And whoso falleth not down and worshippeth, that he should be cast into the midst of a burning fiery furnace. 12There are certain Jews whom thou hast set over the affairs of the province of Babylon, Shadrach, Meshach, and Abed-nego; these men, O king, have not regarded thee: they serve not thy gods, nor worship the golden image which thou hast set up. 13Then Nebuchadnezzar in his rage and fury commanded to bring Shadrach, Meshach, and Abed-nego. Then they brought these men before the king. 14Nebuchadnezzar spake and said unto them, Is it true, O Shadrach, Meshach, and Abed-nego, do not ye serve my gods, nor worship the golden image which I have set up? 15Now if ye be ready that at what time ye hear the sound of the cornet, flute, harp, sackbut, psaltery, and dulcimer, and all kinds of music, ye fall down and worship the image which I have made; well: but if ye worship not, ye shall be cast the same hour into the midst of a burning fiery furnace; and who is that God that shall deliver you out of my hands? 16Shadrach, Meshach, and Abed-nego, answered and said to the king, O Nebuchadnezzar, we are not careful to answer thee in this matter. 17If it be so, our God whom we serve is able to deliver us from the burning fiery furnace, and he will deliver us out of thine hand, O king. 18But if not, be it known unto thee, O king, that we will not serve thy gods, nor worship the golden image which thou hast set up. 19Then was Nebuchadnezzar full of fury, and the form of his visage was changed against Shadrach, Meshach, and Abed-nego: therefore he spake, and commanded that they should heat the furnace one seven times more than it was wont to be heated. 20And he commanded the most mighty men that were in his army to bind Shadrach, Meshach, and Abed-nego, and to cast them into the burning fiery furnace. 21Then these men were bound in their coats, their hosen, and their hats, and their other garments, and were cast into the midst of the burning fiery furnace. 22Therefore because the king's commandment was urgent, and the furnace exceeding hot, the flame of the fire slew those men that took up Shadrach, Meshach, and Abed-nego. 23And these three men, Shadrach, Meshach, and Abed-nego, fell down bound into the midst of the burning fiery furnace. 24Then Nebuchadnezzar the king was astonied, and rose up in haste, and spake, and said unto his counsellors, Did not we cast three men bound into the midst of the fire?

The furnace is used figuratively for the oppression of Egypt, out of which God delivered the Israelites (Deut. 4:2020But the Lord hath taken you, and brought you forth out of the iron furnace, even out of Egypt, to be unto him a people of inheritance, as ye are this day. (Deuteronomy 4:20)); and for the afflictions God afterward brought them into to purify them from their idolatry and sin (Ezek. 22:18, 2218Son of man, the house of Israel is to me become dross: all they are brass, and tin, and iron, and lead, in the midst of the furnace; they are even the dross of silver. (Ezekiel 22:18)
22As silver is melted in the midst of the furnace, so shall ye be melted in the midst thereof; and ye shall know that I the Lord have poured out my fury upon you. (Ezekiel 22:22)
). In the N. T. the furnace of fire refers to the place of eternal punishment (Matt. 13:42, 5042And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth. (Matthew 13:42)
50And shall cast them into the furnace of fire: there shall be wailing and gnashing of teeth. (Matthew 13:50)
