Answer 2

Answer:

Air or oxygen is injected into a hearth under pressure from bellows or a blowing engine or other devices. This causes the fire to be hotter in front of the blast than it would otherwise have been, enabling metals to be smelted or melted or made hot enough to be worked in a forge, though these are blown only with air. This applies to any process where a blast is delivered under pressure to make a fire hotter.

The term (like many technical terms relating to ironmaking) was introduced to England from French with the new technology of the blast furnace and finery forge in around 1500, and was sometimes anglicised as tue-iron or tue iron.[4]
