actually... if you do a search you can find plenty on wrought iron chain... .... -wrought iron being iron made by a reduction process in a bloom furnance... ... - a spongy bloom of iron and silicate slag is produced..... this is then folded and forge welded many times... to squeeze out some of the silicate slags.... and evenly spread out the remaining stringers....
the low grade has lots of large stringers... and used for stuff like wagon wheels... -- if you fold the lower grade many more times.....it becomes more homogenous .... and this is what you would use for chain..... still today... if you want some high grade wrought for knife fittings... you still can get this will large boat or anchor chains..... -- and it is soft... very little carbon in it.... and not hardenable (unless altered) ..... corrosion resistant, and tough, fiberous, .... very desirable for its easy forge welding both of my peter wright anvils have a wrought iron body and a steel plate for the face... and its only a 100 years old... .. so wrought was still used for a long time Greg |
