Is the Iron Age the age when the best things were made out of pure iron? Or is it the later age when the best things were made out of steel (which is iron plus carbon)? And if it‘s the latter, then shouldn‘t it be called the Steel Age?
Your Boyfriend is getting aerated. Chill leave it alone and the air will work its own way out. Always suck brake fluid through the system dont pump it, dont drink it, it causes brain damage.
It is the A.B.S Pump pumpin air into the brakes (seals gone)- Disconnect it and try it. What is it? A mitsi? Also check the rear brake cylinders if they have gone it could do that.
You need to distinguish between pure elemental iron, which is practically useless and was certainly never produced at the time of what we call the iron age, cast iron which is brittle when solid but fluid when melted, and wrought iron which is tougher and approaches the characteristics of what we call steel, but can't be cast as well due to the lower carbon content. The Iron Age made no such distinctions, it was simply the time when it was realized that this ore could be fired with charcoal to form a new metal.
It is the period following the time that people learned to smelt iron, that is, removing it from it's ores. This probably first began in Mesopotamia and people such as the Hittites had a great advantage over their bronze age enemies. Finding metallic iron in nature was a very rare event, probably from meteorites. Steel came latter but at first was made in small quantities, primarily for weapons and armor. Iron was still much more commonly used. It is not as commonly used today but still endures in applications that do not require the strength or hardness of steel and its lower cost such as cast iron and ornamental iron. This became possible when furnaces were invented that made the low-cost production of quality steel possible. See the open-hearth and Bessemer processes for dates.
